President’s Letter

Susan Wager

Looking forward to the coming

year…..with an eye back to the past.

I am looking forward to 2016 and being Presi-dent of the Colorado Section of the AIPG. I at-tended the AIPG National Conference in Alaska this past September and also represented the Col-orado Section at the business meeting. This was my first trip to Alaska and I really enjoyed it, but I also enjoyed meeting the representatives from other sections and hearing about their activities and some of their challenges. One common thread: we need younger people to get involved. This is true, but we have a vi-brant membership now. The membership we have needs to be represented, and encouraged to participate, as well. Many of us, who are more experienced, started out in a time when there was no Facebook or LinkedIn. We found, early on, that professional societies were fun and offered great learning and networking opportunities. Many societies had weekly or monthly talks and lunches, and seminars or courses on various rele-vant topics. Employers encouraged people to at-tend these events and paid the costs. This wasn’t just fluff, or an excuse to get out of work, these society meetings were really an important part of learning what it meant to be a professional geolo-gist. Not that Facebook, LinkedIn, and You-Tube aren’t great tools, they are. I use all three and I hope to see the Colorado Section get a Facebook page up and running soon. But there is an ele-ment of personal face-time interaction that is missing. The Colorado Section ExCom has been struggling with finding a venue, format, and time to have some talks or other activities to draw the membership together. There are several challeng-es, but it basically comes down to time. People

can get instant feedback on the internet, and have a difficult time scheduling two or three hours away from the office to attend a lunch talk or some other event. This is particularly true of the younger professionals, who also may not be get-ting the support they need from employers, and also have families that need attention. I hope we can use the internet tools to reach out to all of our members, especially the younger ones, with some timely information on activities and on legislation that may have an impact on our membership. I want everyone to see just how important the AIPG and other professional socie-ties are to them. The AIPG is different from many of scientific societies since we are incorpo-rated as a 501(c)(6) instead of a 501(c)(3). This means that we have the ability to be involved in the legislative arena. Towards that end, the AIPG Colorado Section has a lobbyist, Betsy Murray. We have a diverse organization and there is pro-posed legislation that impacts much of our mem-bership during each legislative session. Betsy does a great job of keeping track of upcoming legislation and the potential impacts it could have to our members. I want to see our Facebook page used to get this information out in a more timely manner than is possible with the newslet-ter so that the members can contact the ExCom with concerns, or their elected representatives directly. The AIPG Colorado section is hosting a Legislative Reception this February to provide a setting for businesses and professionals to inter-act with their elected representatives. This newsletter is a very important avenue of communication. This was apparent at the nation-al meeting when all sections and all ages and all

(Continued on page 4)


Looking Back It has been 20 years since I last served as the Colorado Section’s Editor in a run that lasted from 1992 to 1996. Back then the Colorado Pro-fessional Geologist (CPG) was a monthly that was mailed out. I introduced the use of Microsoft Publisher software to format the CPG and echoes of those issues remain today. But a great deal has changed. Now the CPG is a quarterly containing more pages per issue and includes color in a vari-ety of ways reflecting the changes in digital pho-tography and printing in the past 20 years. Distribution of the CPG is now largely via email, not via printed and mailed. Sue and I used to have to get a bunch of copies printed and get address labels from AIPG HQ, which we then applied to each copy. We had a printer who would do the bulk mailing. This distribution method change resulted in significant and posi-tive change in the Colorado Section’s budget. Looking Ahead Now there is pressure to include hyperlink and distribute in web format rather than in PDF. I’ll tiptoe into this new method of presentation, which doesn’t have a fixed format layout, one of the great advantages of PDF files that allow eve-ryone to agree that we’re looking at say, the sec-ond paragraph on page 10. This issue adds a new student abstract section in which we’ll include contributions from our student members. Hopefully there won’t be too many for each issue. This issue continues to in-

troduce new members of the Section’s Executive Committee, this month Joe Brinton and Mark Mathisen. I’m pleased that the number of new or relatively new members of the Section ExCom continues to increase. Logan MacMillan and I were ExCom members in 1992 and while we contribute valuable institutional memory, we’d like to have younger folks replace us. Please con-sider submitting your own picture and short bio for our member biographies section. Legislative Reception The Colorado Section is hosting its biannual Legislative Reception on March 8th. Please in-vite your Senator and Representative and come; see details on page 5.

of our diverse population said that the TPG and their sections newsletters were important and that they wanted hard-copy, as well as soft-copy, to be available. There is something about having that hard copy format available to take with you or as a give-away to others. There are also differ-ent advertising opportunities available in the newsletters, as well. Finally, many of us are experiencing some difficult times as the oil and gas and the mining sectors continue to be in a slump. Some of us re-member the 80s in the oil and gas industry and have been through this before. It will likely also

(President’s Letter continued from page 3) impact those in environmental and civil engineer-ing professions, eventually. My own personal experience is that staying connected through pro-fessional societies is critical to surviving hard times. I welcome any suggestions as to how the AIPG Colorado Section can help people through these tough times. Look for more news on various activities, such as field trips, talks, the annual picnic, as these things are scheduled. As always, the AIPG CO ExCom is here to serve the membership, and we encourage and welcome suggestions for ac-tivities that

Editor’s Remarks David M. Abbott, Jr.

David and Sue Abbott during the 2015 Anchorage meeting.


The Colorado Section of AIPG sponsors this event for our membership to encourage their contact and interaction with their state legisla-tors. We enthusiastically invite our fellow pro-fessional societies whose members practice in allied and parallel practice fields using the geo-sciences. The venue, the University Club is just a few blocks north of the Capitol and offers a re-laxed environment with exhibitors’ displays that cross the spectrum of industrial, academic and scientific practice disciplines. The catering and refreshments offered will be light hors d’oeuvres and a cash bar. Hosting societies are encouraged to ask their members to: 1) contact their legislators well be-forehand, asking to meet them at the reception, and 2) follow-up with an email thanking them for attending. Attendees will be asked for a contribution of $20/person at the door to help cover expenses. Information for sponsors and exhibitors will be provided by contacting [email protected] or 303-241-2572. FINDING YOUR LEGISLATOR Our State Legislature offers great access through their website: http://www.leg.state.co.us/clics/cslFrontPages.nsf/HomeSplash?OpenForm. Once at that site, under Contact Information/Who is My Legislator?, you will connect to: http://openstates.org/co/. It uses maps to identify an address (presumably yours), which leads to identification and contact information for that legislator, including Capitol Office address, phone and email address. TIPS ON TAKING ACTION THIS LEGIS-LATIVE SESSION There are no specific issues that Leg/Reg is formally following at this time. The Section’s

lobbyist, Betsy Murray, is monitoring several items through the JBC hearings, including specifically funding for the Geological Survey. There have not been any issues that the Board has adopted in the last 2 years. We did consider a position suggested to us by a ‘trade group’ and declined to support their language. Gossip: Some in the media are suggesting that this fall’s 2016 election will likely have ‘fracking’ issues on the ballot. Some legislators have been quoted in the media as saying the Governor’s Task Force didn’t resolve anything on ’critical issues,’ insinuating there will be more proposed legislation this upcoming session and citizen initiatives for the fall election. The Section’s Legislative Reception committee, with the help of two seasoned veterans, Ron Pritch-ett and Larry Anna, who was just announced as a recipient of the Public Service Award from AAPG. WHAT IS THE BEST WAY TO ADVOCATE? The Colorado General Assembly Convenes on January 13th. While the legislature is in session, you may receive emails encouraging you, as a pri-vate citizen, to take some specific action on an is-sue or position. When we respond to calls to action we are, in effect, lobbying. We are advocating that our legislators take a specific position on an issue, Legislators have minimal staff support while the legislature is in session, and they have NO staff when not in session. This makes it challenging to respond personally to all contacts. Email is often the best way to communicate with your legislator. Tips provided for effective email included: x� put the bill number or subject matter in the sub-

ject line x� make the email short and to the point x� if there is a personal story relevant to the issue

include it x� use bullet points when possible. Happy Advocating! (From the Jeffco League of Women Voters, Janu-ary 2016 Voice)

I’m a mining geologist and also a 4th genera-tion Coloradan. In the West, water is for fighting over. My Great Grandfather and Grandfather looked at exploiting the Fraiser River sources waters in the early 20th century without success. Colorado is noted for being the source of ma-jor rivers: the Platte (North and South), the Ar-kansas, the Rio Grande, and the major Colorado River tributaries: the San Juan, Animas, Delores, Gunnison, Colorado, White, and Yampa. The Green does flow through northwestern Colorado but doesn’t currently affect Colorado’s water supplies unlike its major tributary, the Yampa. Most of Colorado’s surface water falls as snow and rain in the greater Colorado River drainage area known as the Western Slope, while most of the population is on the Eastern Slope, particular-ly in the Front Range Corridor between Colorado Springs and Wellington (almost to Wyoming). Trans-mountain diversion of water across the Continental Divide begins with the Grand Ditch along the east side of the Never Summer Range on the northwest boundary of Rocky Mountain National Park that flows across the Continental Divide at La Poudre Pass, 10,182 feet, and into the Cache La Poudre River drainage. This is fol-lowed by the large Colorado-Big Thompson Pro-ject (C-BT) that connects Grand Lake, the source of the Colorado River prior to the C-BT in south-western Rocky Mountain National Park, with Es-tes Park and the Big Thompson River on the east side of the Park, the Pioneer Bore of the Moffat Tunnel from the Fraser River sources near Win-ter Park into South Boulder Creek, the Roberts Tunnel from Dillon Reservoir to the North Fork of the South Platte, and the Frying Pan-Arkansas Project in central Colorado. But these surface water diversions fill only part of Colorado’s wa-ter needs along the Front Range Corridor. The rest comes from groundwater sources both shal-low and deep. As a Coloradan, water is an im-portant topic. The American Ground Water Trust of Con-cord, NH holds an annual groundwater confer-

ences in Colorado and elsewhere around the country. These conferences bring together the hydrologists, water engineers, water supply com-panies, well drillers, regulators, NGOs interested in water issues, County Commissioners, state Legislators, and interested folks like me for day-long sessions on the groundwater issues of the particular region. I attended the conference in Denver on December 4, 2015. AIPG was a “cooperating organization,” one of those interest-ed NGOs, which provided a reduced registration rate to members. It was an interesting day. The focus was on northeastern Colorado. The meeting addressed a variety of topics from a variety of perspectives. In the first talk addressed representatives of Colorado Water Wise and the Colorado Foundation for Water Ed-ucation presented some of their programs for citi-zen education and outreach. Colorado Water Wise’s Live Like Y ou Love It campaign reminds everyone that “we all live downstream. What happens upstream affects those downstream.” the Colorado Foundation for Water Education pub-lishes the quarterly Headwaters magazine for cit-izens; visit their website www.yourwatercolorado.org to review and sub-scribe. Other presentations addressed: x� The new Colorado Water Plan

x� Reducing dependence on nonrenewable groundwater and changing the way we use the Denver Basin aquifer

x� The impact of gravel pit storage on ground-water-surface water interactions

x� The problems in Weld County resulting from the requirement to add water to aquifers that are already full leading to basement flooding and other problems

x� Securing a dependable groundwater supply for the agricultural industry

x� The treatment challenges presented by the Gold King Mine release and other mine drain-age areas

x� The impacts on groundwater from hydraulic fracturing—groundwater contamination has not occurred

x� The role of local government in maintaining water security for agricultural production

I came away from the meeting with two main impressions. First, the water side, particularly the water sources side, of the geoscience business is healthy and growing, unlike most of the rest of the geoscience specialties. And second, American Ground Water Trust’s conferences are worth at-tending for anyone interested in water supply is-sues, which should be all of us. I urge you to look at the http://lovecoloradowater.org/ and the https://www.yourwatercolorado.org/ websites for general information on Colorado’s water for both your own and your neighbor’s edification.

Water Use in Colorado

14 Ways to Care

for Water Quality

1. Know where your water goes—water used inside your home goes to a treatment plant; water used outside is not.

2. Use fertilizers and pesticides sparingly—check your soil through extension office to see if fertilizer is needed. Consider hiring a professional application when necessary.

3. Pick up pet poop—there is no poop fairy. Pet waste washes into our storm drains and pol-lutes our rivers.

4. Fix the oil leak—car leaks can spread oil into the water supply.

5. Use a commercial car wash—a commercial car wash that recycles water is more water efficient and does not send soapy water down the driveway and into the storm drain.

6. Don’t feed the storm drains—no oil, pesti-cides, fertilizers, paints, trash, grass, leaves, household waste, etc.

7. Direct your downspout—point to lawns or shrubs, not sidewalks.

8. Dispose of medicine properly—don’t flush it. 9. Plant rain gardens—visit the Colorado State

University Stormwater Center to learn more. 10. Reduce paved areas—replace with porous

materials that will allow water to soak through.

11. Compost—healthy soil acts a water filter. 12. Sweep—sweep storm runoff from dirty side-

walks and streets to avoid them being washed into storm drains and streams.

13. Use sand or cat litter—use natural materials rather than salts; sweep off after ice has melt-ed. Remember that cat litter is made from low-grade drill mud, so don’t get too wet.

14. Follow directions for storage and use of all household chemicals.

Applications of LiDAR and field reconnaissance in the rapid assessment of karst-based surface morphology, Coconino National Forest, Arizona Kyle Rowinski, Geological Society of America GeoCorps Program, Summer 2015 , University of Northern Colorado, [email protected] Subsurface analysis using data obtained from an aerial platform may be regarded as impractical, how-ever recent advancements in Very High Resolution (VHR) remote sensing have rendered the collection of terrain data with a vertical resolution of up to 30 cm highly feasible. Obtained via a process termed Light Detection and Ranging (LiDAR), data collected provides a 3-dimensional representation of sur-face morphology with high resolution. Input of LiDAR data into geospatial analysis software such as ArcMap or ArcScene allows for the identification of subtle topographic changes across a land surface. Considering subsurface processes often have observable effects on the surface, a thorough examination of LiDAR terrain data may provide the basis for conclusions regarding subsurface dynamics. Of partic-ular interest is the application of LiDAR in the investigation of karst topography; terrain characterized by sinkholes, surface depressions and areas of subsidence as a result of the dissolution and collapse of underlying soluble rock units. Karst features offer points of recharge or discharge for associated aqui-fer systems, and are therefore considered important geologic resources. Geospatial analysis of LiDAR data is a preliminary step in the examination of karst topography; potential karst feature locations may be identified and input into a geodatabase. Subsequent field assessment of potential karst features may involve a rapid, broad-scale inventory, or require an in-depth, localized geologic analysis of a specific feature. The former is both time and resource conserving, and allows for a high number of features to be surveyed in a relatively short timeframe. Thus, federal agencies such as the United States Forest Service may incorporate a rapid karst inventory and assessment into a forest resource management and conservation project. Such is the case on the Coconino National Forest, where LiDAR data was used to facilitate a recent cave and karst survey, conducted by participants of the Geological Society of Ameri-ca’s GeoCorps America program. http://www.karstportal.org/node/21825 Editor’s comment: LiDAR “sees” through vegetation and reveals features not visible in standard air-photos, etc. Vince Matthews showed some LiDAR images of the Twin Lakes and Leadville areas in his January 8th Annual Dinner presentation on Colorado’s glacial and periglacial features.

Editor’s note: the Student Abstracts section of the Colorado Professional Geologist is a new feature that is intended to highlight research work done by our student members. Submissions may include a picture or diagram or two if particularly illustrative. The abstract should also indicate where it was published or the paper was presented. There will be a limit on the amount of pages that can be devoted to student abstracts, which may vary by issue.


Using Specific Gravity to Determine the Solid Solution Variation of K+, or Na+ and Ca2+ in Feldspar Hand Samples Tim Olsen, EAS Department, Metropolitan State University of Denver, now at the University of Northern Colorado, 2015 AIPG Annual Meeting in Anchorage, AK. Plagioclase and alkali feldspar minerals have slightly varying specific gravities, due to changing chem-ical compositions within their respective solid solution and exsolution series. While quantitative chem-ical analysis in investigating compositions is desirable, it is either confined to the laboratory or requires expensive field instruments. However, advances in inexpensive load cell scale technology has led to the development of pocket scales that can be used to make rapid, precise field measurements of specif-ic gravity (SG) on rock and mineral samples using a single pan hydrostatic method (Kackstaetter, patent pending). Accuracies such attained show enough resolution to enable differentia-tion in chemical compositions of feldspar samples. Specific gravity measurements were performed on known feldspar species and data was scrutinized through regression analysis. Additionally, geochemi-cal data of each sample was obtained through acid digestion and Flame Atomic Absorption Spectros-copy to determine the exact proportions of K+, or Na+ and Ca2+. Trend line regression for solid solution plagioclase samples as well as alkali feldspar exsolution series can now be developed to relate the spe-cific gravity to the chemical composition of each sample. Densities can now be assigned to exact chemical compositions within feldspars. By using the field portable single pan hydrostatic method for SG determination, an accurate and rapid identification of specific feldspar species is now possible.

I was born and raised in a small town outside of Salt Lake City, Utah. Growing up, I pursued various outdoor activities such as skiing, rock-climbing, hiking, spelunking, and mountain bik-ing. As a teenager, I had the opportunity to ac-company a geologist in sampling springs for wa-ter quality analysis. I distinctly remember think-ing “People get paid to go hiking around explor-ing the hills all day? Sign me up!” I attended Brigham Young University and earned a bachelor’s degree in Engineering Geol-ogy, after which I attended the University of Alaska, Fairbanks and earned a master’s degree in Structural Geology. Due to a lull in the energy and mining sectors at the time of graduation, I worked for the U.S. Geological Survey and later for the U.S. Forest Service as a hydrologist. When the energy sector rebounded, I was able to find a career in mining. For the past 10 years I have been employed in the coal mining industry. I have been involved with greenfield exploration, brownfield explora-tion, resource/reserve evaluation, underground mine production, coalbed methane degasifica-tion, directional drilling, geophysical analysis,

structural analysis, environmental analysis (NEPA), geotechnical engineering, and mine ven-tilation. Work locations have included Greenland, Canada, U.S.A., and Brazil. I have enjoyed the breadth of experiences gained as a geologist, from

The Colorado Section is looking for member biographies to run in the newsletter, similar to the ones included in previous issues for members of the current Executive Committee and other active Section members. We want the members to know about other members whom they may not have met.

This will be an ongoing item for the newsletter, so please feel free to send in your short biography (preferably no more than 350 words) and we will run them as we get them and space is available. A photo would also be nice to include, if you have one available. Thank you in advance for participating in this part of the newsletter!

(Brinton, continued from page 12)

I was raised the son of an exploration geolo-gist and during the early years of my life as my father’s career advanced, we moved every year, resulting in new schools, friends, towns and ad-ventures. We finally settled in Golden, Colorado in 1969 and over the next several years I contin-ued on occasions to accompany my dad when he travelled. It was on these exploration trips that I developed an interest in how geology taught one to read the rocks to uncover the past and a life-long passion to see the world. I eventually found myself at the Colorado School of Mines where I obtained a degree in Geophysical Engineering in 1984 and began a 15 year career in the uranium exploration and min-ing industries. During a down turn in the mining industry in the late 1990s I had the unique oppor-tunity to change careers and try my and in the telecommunication industry as Lead Engineer and Project Manager in the development and im-plementation of network reliance systems, though I never could get the exploration bug out of my system. In 2006 I returned to the exploration and min-ing industry as Senior Project Geologist for Den-ison Mines eventually becoming Director—Project Resources overseeing resource evalua-tions for projects in the USA, Canada, Africa and Mongolia. It is at this time I became involved with AIPG. I joined Roscoe Postle Associates; a Toronto Canada based Mining Consulting Com-pany in May 2014.

As my career has taken me to work on five of the seven continents, from the deserts of south-west USA to the steppes of Mongolia I continue to be fascinated by what the rocks are telling us. I look forward to increasing my involvement in AIPG and serving as a member of the CO-AIPG Board in 2016.


The Colorado Section’s Rex Monahan Geo-logical Scholarship Fund was started by gener-ous gifts from Rex Monahan of Sterling, CO.

UNC Seeking Internship Sites The Earth and Atmospheric Sciences Depart-ment at the University of Northern Colorado is seeking internship sites for our undergraduate and graduate students, including our new Profes-sional Masters Program. We recognize the inval-uable experience gained by our students in the real world where they can apply their geosci-ence, atmospheric science, and/or environmental science knowledge and skills. Indeed an intern-ship is now either a program requirement for graduation or a very strongly recommended elective. In order to give you confidence in the prepa-ration of our students for an internship with your firm, the department and our student(s) will

x provide a resume from the prospective internship candidate,

x provide contact information for a pro-fessor in our department familiar with the student, and

x condition your acceptance of an intern-ship candidate upon an interview if you so desire.

The internship program requires an “agreement” for internship be signed by the Uni-versity of Northern Colorado and you. We pro-vide the agreement template to you that specifies who does what. If you elect to pay the student for their internship, they become your employee

and your worker’s compensation takes effect; if you elect not to pay the student, you are not respon-sible for their worker’s compensation insurance. Once that agreement form is completed the intern-ship can start; internships may be completed either during the academic year or during the summer. The student is required to work with you for 37.5 hours per academic credit. Students can register for between 1 and 12 credits. For example, a 3-credit internship would be required to complete 112.5 hours (equivalent to about 15 eight hour days). We anticipate this would be sufficient time to train the intern to be able to provide you with useful work to assist your firm and for the intern to gain experi-ence as a working scientist. Please visit our department (virtually) at http://www/unco.edu/nhs/esci/ or in person when you are in the area! Please contact me at the numbers below if fur-ther information is needed or to discuss internship collaborations between our department and your firm.

2016 Educational Sponsorship Effort Tom Van Arsdale, CPG 11073

For the first time in a number of years, the Colorado Section undertook an effort to raise funds for our educational endeavors by offering company/individual advertising within the CPG to those provid-ing financial support. The CO-Section educational sponsorship effort provides funds for a number of deserving programs, including: Annual Student Scholarships; Annual Student Chapter Grants; and Public Outreach Programs, such as; Dinosaur Ridge events, the Annual Colorado Science and Engi-neering Fair, and the Annual CO-AIPG Legislative Reception. The CO-Section Board would like to thank the following companies/individuals for their much need-ed support: Anadarko Petroleum Corporation, Pershing Gold Corporation, Condor Consulting In-corporated, Peters Geosciences, and David M. Abbott, Jr. Furthermore, the entire CO-Section Executive Committee would like to remind its members to sup-port our Section sponsors. Consider working with these companies, and when you speak with their representatives, let them know that you appreciate their sponsorship of our Section.


Annual Dinner 2016 Vince Matthews

Colorado’s Glacial & Periglacial Features The Annual Section Dinner was held Janu-ary 8, 2016 at the White Fence Farm. About 30 Section members, spouses, and students from the MSU Student Chapter and Prof. Bill Hoyt from UNC attended. Dr. Vince Matthews gave a very interesting and detailed review of Colorado’s glacial and periglacial features. Colorado has a number of world-class examples of Alpine glaciation and related features. One of Matthews’ points that is not gener-ally appreciated is that the current glaciers, permanent snowfields, rock glaciers (perigla-cial), etc. are from the Little Ice age that oc-curred from around 1350 to 1850 and are not remnants of Pleistocene glaciations. The Pleis-tocene glaciers melted by 13,000 years ago. Outstanding examples of terminal and lat-eral moraines are found at Turquoise Lake SW of Leadville and in the Grand Lake and Shad-ow Mountain area of southwestern Rocky Mountain National Park. Matthews noted that one of his textbooks from 1960 included an exercise based on Turquoise Lake that re-mains in the current, 17th edition of the same text. LIDAR images reveal excellent infor-mation about moraines of both Bull Lake and Pinedale ages, Rocky Mountain National Park has many outstanding examples of glacial and periglacial features, many of which can be viewed from Trail Ridge Road. Colorado is also home to over 4,000 rock glaciers, a significant percentage of the total known rock glaciers. There are many of these periglacial features are in the San Juan Moun-tains and the flanks of Mount Sopris contains outstanding examples; see picture on then next page. The youngest rock glacier formed in the pit of the Climax Mine during a period of in-activity; picture next page. Like true glaciers, rock glaciers have measureable downslope flow. They may be either rock covered glacial ice or contain interstitial ice between the rock fragments.

Consider contributing to the Rex Monahan Geological Scholarship Fund. Why? The Colorado Section’s Scholarship Fund is growing slowly with other members’ contributions. The Scholarship Fund was established to support one or more undergraduate and/or graduate students in Colorado as they pursue geological degrees. The Section is working to build the fund to a point where it can provide consistent funding for at least one award to one student and eventually sustain itself at the same time. From one award, we expect to expand the fund and award more students.

Please support the students who are the future of

the geologic profession.

********************************************** ; YES!
