Introduction
The geologic history of Little Cottonwood is expansive and informative to what our Earth once was.Little Cottonwood Canyon has it all: From Geology, to the history of mining, to water rights, to being a huge contributor to Utah’s economy.

-Little Cottonwood Creek is one of the principal streams entering the Salt Lake Valley.-Cecret Lake is the headwater of Little Cottonwood Creek.

-The Watershed in Little Cottonwood Canyon in protected as a drinking water source but it is used for recreation as well.-The US forest service has implemented regulations that the ski resorts must follow to protect the watershed.

Ski Link
• Although the skilink does not involve Little Cottonwood Canyon it still affects our watershed.
• 30 acres of watershed and US public land would have to be sold to a private company.
• Would connect The Canyons Resort to Solitude Resort.
• Very controversial due to its said impact on the environment.
• Could boost Utah’s economy, and lessen the greenhouse gases created from the millions of miles driven per year.

The History of Alta Township
1904- Most mines are split between 3 mining companies: Wasatch Mines, Alta United, and Michigan-Utah.
1919- A new railroad to Alta is made, replacing the old mule-drawn rail.
1920- Because of the depression, most mines shut down for business.
1935- Alta is seen for it’s potential to become a skiing area.
1936- A road to Alta is constructed.
1937- 1,800 acres are given to develop a ski area.
1939- The Stilwell store becomes the Snowpine Lodge. All-day passes cost $1.50.

Geology
• U-Shaped canyon was formed from a glacier that flowed into Lake Bonneville about 30,000-10,000 years ago
• The Wasatch fault is a dramatic cut in the foothills of the mouth of the canyon.~30 feet
• The igneous intrusion is from a string of plutons that start in Park City and end at the Oquirrh’s. Hence all the mines.

Lower Canyon
• Contact zone of the BCCformation and LCC stock.
• BCC formation consists ofslate and “rusted” quartzite.
• LCC Stock consists of quartzmonzonite. Salt and pepper.

Significant Geologic Features
This area contains Mineral Fork tillite which provides evidence of “Snowball Earth” ~1.5 Ba.Above the Tintic Quartzite is signature band of white dolomite unconformity~200 million years of missing time.

Snowbird
“The Bird” giving the environment the bird.
• Snowbird proposed to develop more south into Mineral Basin and Mary Ellen Gulch.
• Snowbird wants to expand from the top of their existing Tram; Hidden Peak to American Fork Twin peaks.
![Page 13: Little Cottonwood Canyon By: Laura Sipos, Cami Duckett, Alara Roberds, Jake Minardi, Courtney Watson.](https://reader036.fdocuments.in/reader036/viewer/2022062803/56649f465503460f94c68555/html5/thumbnails/13.jpg)
• Just because the snowbird expansion would be outside of the Salt Lake City watershed doesn’t necessarily make it watershed friendly.
• With 780 acres of new skiable terrain, more people would go to the canyon. There is more impact upon the watershed as a result of more people in the canyon.

Save Our Canyons“Dedicated to protecting the beauty and wildness of the Wasatch canyons,
mountains, and foothills.”
• Non-profit organizaton
• Almost entirely volunteer based
• Fights against commercial and residential development in the canyons.

Wilderness Facts
• Utah population within 15 miles of Wasatch: 85%
• Residents benefiting from the Salt Lake Watershed: about 400,000
• Current Salt Lake County wilderness acres: 37,045
• Save Our Canyons proposed acres: 28,176
