Pyramid Peak is a fourteen-thousand-foot mountain in the U.S. state of Colorado. It is the 47th highest mountain peak in Colorado, and 78th highest peak in the United States. It is located in the Elk Mountains in southeastern Pitkin County, approximately 12 miles (19 km) southwest of Aspen. The summit somewhat resembles a ragged square pyramid and is visible from the Roaring Fork River valley north of Aspen along the canyon of Maroon Creek. Like many of the peaks in the Elks, Pyramid Peak is quite steep, especially compared to more gentle fourteeners such as Mount Elbert. For example, the peak's summit rises 4,000 feet (1,200 m) above Crater Lake to the northwest in only 1.2 miles (1.9 km), and 4,400 feet (1,300 m) above East Maroon Creek to the east of the peak in the same horizontal distance.

The Snowmastodon site, also known as the Ziegler Reservoir fossil site, is the location of an important Ice Age fossil excavation near Snowmass Village, Colorado. Fossils were first discovered on October 14, 2010, during the construction of a 5 hectares (12 acres) reservoir to supply Snowmass Village with water. Over the subsequent weeks, after an agreement had been reached to allow paleontological excavation, crews from the Denver Museum of Nature & Science and the U.S. Geological Survey worked along with the construction crews as more fossil material was uncovered. The site closed for five months over the winter, reopening May 15, 2011. Between May 15 and July 4, 2011, crews from the Denver Museum of Nature & Science conducted a large scale fossil excavation alongside construction crews building a dam for the reservoir. In total over 36,000 vertebrate fossils (including mammoths, mastodons, ground sloths, horses, camels and deer), more than 100 species of fossil invertebrates and over 100 species of fossil plants were found in sediments deposited by an alpine lake during the last interglacial period.
