ALSO: thE BLACK CANYON n PARADE OF LiGhtS
From the EditorLast August 22, Colorado had an earth-
quake. Not a big one by global standards, but it was a reminder that geology is happening here every day.
Nowhere is Colorado geology — as an event, not just a science — more visible than in the settings for two of this month’s stories, coincidentally on the far side of the state from the earthquake. it’s a statewide phenomenon.
the Black Canyon of the Gunnison formed when an upheaval pushed hard rock into the path of a rushing river, leaving a crevasse which time and erosion have not softened.
the high country of the San juan Moun-tains is the result of more volcanic uplift, and provides a perfect setting to show off Colo-rado’s autumn aspens at their most glorious.
Enjoy this last issue of 2011 —and come on back in 2012. Some more geology is sure to happen.

Three mil-lion years ago, the Gunnison River in southwestern Colo-rado flowed across a valley of soft volcanic ash.
then geology happened.
the valley floor began to uplift into a dome of rock, and the river started carving a canyon through the soft ash surface. By the time the river reached the harder meta-morphic rock layer underneath, it was trapped in its course and could not divert around this much tougher material.
Like a bandsaw pressed against a board, the river cut vertically down-wards, with relatively little erosion to the sides, leaving a 48-mile-long, hard-walled, narrow gash through the schist,

The green waters of the Gunnison river cut through The narrows, where the canyon floor squeezes down to widths as small as 40 feet. The river drops 90 feet per mile through the national Park, giving it its cutting power.

gneiss and pegmatite that now reaches depths of over 2,200 feet.
today, 12 miles of the canyon’s deepest part form the Black Canyon of the Gun-nison National Park (a National Monu-ment from 1933 to 1999).
The name comes not from the color-ing, which is grays, browns and dark pinks, but from the perpetual shade in the depths, cast by the sheer walls.
At points, the walls are separated by only 1,500 feet at the rim (and as little as 40 feet at the river). But it takes two hours and 50 miles of driving to travel that 1,500 feet — out of the park, around the uplift, and in from the
other side. Access to the
canyon floor is via strenuous hikes or technical descents of the steep walls, or by kayak along the river from the eastern end of the park., where a road with a 16% grade descends to river level. n

At its western end, the Black canyon widens to form the Gunnison

Colorado’s San juan Mountains and the Million-Dollar highway

along the Million-Dollar highway (lower left) below red Mountain
Pass, south of Ouray.
STORY & PhOTOS
By AnDy PIPErs the crow flies, it is only a bit over 50 miles from Ouray, Colorado to Du-rango.
But that 50 miles climbs over
the top of the San juan Mountains, a sprawling mass of volcanic upthrust rich in minerals, no-tably silver and gold.
the road is
known as the east-ern half of the San juan Skyway, or u.S. 550, or “the Million-Dollar highway.”
Opinions vary as to whether the A
latter refers to the value of the precious metals beneath, or the cost of its rug-ged construction, or the incredible views from its 11,000-ft
passes.But never is its
value more obvious to the eye than in autumn, when it overlooks mile after mile of sweeping
golden panoramas — and becomes the “Million-Aspen highway.”
South the road climbs: from Ouray to Red Mountain
Pass, through the Chattanooga Valley, past the historic mining town of Silverton, above the tree line at Molas Pass (10,910 feet)

and Coal Bank Pass, and then a long descent through the valley of the Animas River to Durango.
The view chang-es with each turn of the highway: from broad mountainsides on which 50-foot aspens become but tiny specks of pollen; to high ridges where passing clouds ob-scure the mountains and leave the trees silhouetted against nothingness.
From picture-perfect scenes of the San juans surround-ed by golden frames — to the heart of Silverton, where golden hillsides backdrop the San juan County court-house spire, and fallen leaves literally pave the streets with gold. n

Even the low clouds of a clearing snowstorm can’t dim the sea of yellow along the highway.

PARADE OFWhat Macy’s thanks-
giving Day parade is to New York, the Parade of Lights is to Denver. the sure sign that the winter holiday season has begun.
Bedecked in Christmas-tree lights, bands from the city’s high schools and the state’s major universities,
and floats sponsored by civic groups and businesses, gather at the Civic Center and march through downtown to the sounds of Christmas carols.
the electric lights are a part of Denver’s history, since the city was one of the first to adopt electric street and decorative lights in the 1880s, earning Denver the nickname “City of Lights.” n
