For example, amazonite can be found next to Barr Trail, the main hiking route to the summit of Pikes Peak. The most famous collecting area on the Peak is Glenn Cove, a glacial cirque located at 11,000 feet (3,400 m) on the north side of the mountain. Quartz crystals, amazonite and topaz crystals can be found in pockets on steep cliffs in this area.
Pikes Peak granite is a 1.08 billion year old Late-Precambrian geologic formation found in the central part of the Front Range of Colorado.It is a coarse-grained pink to light red syenogranite with minor gray monzogranite, and it has a distinctive brick-red appearance where it outcrops.
Quartzite. Quartzite is a hard, non- foliated metamorphic rock which was originally pure quartz sandstone. [1][2] Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and ...
The Medicine Bow Mountains are a mountain range in the Rocky Mountains that extend 100 miles (160 km) [2] from northern Colorado into southern Wyoming. The northern extent of this range is the sub-range the Snowy Range. [3] From the northern end of Colorado's Never Summer Mountains, the Medicine Bow mountains extend north from Cameron Pass ...
The Eureka Quartzite is an extensive Paleozoic marine sandstone deposit in western North America that is notable for its great extent, extreme purity, consistently fine grain size of Quartzite, and its tendency to form conspicuous white cliffs visible from afar. The Eureka is commonly underlain and overlain by contrasting slope-forming ...
Franktown Cave is a rock shelter 198 feet (60 m) above Willow Creek, a tributary of Cherry Creek that flows into the South Platte River at Denver, Colorado, 25 miles to the north. It is more than 6,000 feet (1,800 m) in elevation. [2]: 6. Situated on Palmer Divide, which separates the South Platte River basin from the Arkansas River basin ...
The Dome Rock Mountains are a north-south trending range about 30 miles (48 km) long. The Palo Verde Valley borders the range on the west, adjacent to the Colorado River. Interstate 10 bisects the range connecting Ehrenberg on the Colorado River with Quartzsite to the east of the mountains. Quartzsite lies on the western edge of the La Posa ...
The geology of the Grand Canyon area includes one of the most complete and studied sequences of rock on Earth. The nearly 40 major sedimentary rock layers exposed in the Grand Canyon and in the Grand Canyon National Park area range in age from about 200 million to nearly 2 billion years old. Most were deposited in warm, shallow seas and near ...
