This is about the Crater Lake in Pitkin County, Colorado. According to the US Geographic Names Information System, there are also "Crater Lakes" in the following Colorado Counties: Alamosa, Archuleta, Delta, Garfield, Gilpin, Grand, Larimer, Rio Blanco, and San Juan.Crater Lake is a mountain lake in the Elk Mountains, Pitkin County of the US State of Colorado. It lies just northeast of the Maroon Bells and just northwest of Pyramid Peak. The view of the striated Maroon Bells from Crater Lake and the view from nearby Maroon Lake are two of the most photographed mountain scenes in the United States.

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.

Sievers Mountain is a 12,786-foot (3,897 m) summit in Pitkin County, Colorado, United States.

Snowmass is a ski resort located in the Town of Snowmass Village near Aspen, Colorado. The ski area is owned and operated by the Aspen Skiing Company as part of the Aspen/Snowmass complex. It was opened on December 17, 1967 . Snowmass is the largest of the four Aspen/Snowmass mountains, comprising 3,362 acres (1,361 ha).

The Rocky Mountain Biological Laboratory (also known by its acronym RMBL — pronounced 'rumble') is a high-altitude biological field station located near Crested Butte, in the abandoned mining town of Gothic, Colorado in the West Elk Mountains. The laboratory was founded in 1928. Research areas include the ecology of the region, climate change, pollination biology, and a long-running study of the yellow-bellied marmot. The laboratory offers courses for undergraduate students, including National Science Foundation-funded REU students, and provides support for researchers from universities and colleges.

Gothic Mountain is a prominent mountain summit in the Elk Mountains range of the Rocky Mountains of North America. The 12,631-foot (3,850 m) peak is located in Gunnison National Forest, 1.1 miles (1.8 km) west by south (bearing 260°) of the ghost town of Gothic in Gunnison County, Colorado, United States. Gothic Mountain takes its name from its pinnacles said to resemble Gothic architecture.

Highland Peak is a 12,381-foot (3,774 m) mountain summit in Pitkin County, Colorado, United States.

The Roman Abramovich Wildcat Ridge house is a 14,300-square-foot (1,330 m2) mansion at Wildcat Ridge near Snowmass Village, Colorado. The 11-bedroom, 12-bath mansion, and 200 acres (81 ha) of land it stands on, called a "ranch" by The Wall Street Journal, have an estimated worth of $50 million as of 2022, and was owned by Roman Abramovich. He bought the property for $36.375 million in 2008, at the time the third most expensive residential real estate transaction in Pitkin County, Colorado.Built in 2004, the architect was Bart Voorsanger, who also designed the Asia Society Museum in Manhattan.Media reported that the property could be subject to sanctions by the United States government during the 2022 Russian invasion of Ukraine. County commissioner Greg Poschman asked Colorado Deputy Attorney General Kurtis Morrison to investigate why sanctions to date did not target the property, stating to media his question was "if there was illegal activity and the [United States government] overlooked it for some reason".

Snowmass Village is a home rule municipality in Pitkin County, Colorado, United States. The population was 3,096 at the 2020 census. A popular winter resort location for skiing and snowboarding, the town is well known as the location of the Snowmass ski area, the largest of the four nearby ski areas operated collectively as Aspen/Snowmass. In 2010, the accidental discovery by a bulldozer operator of fossilized elements of a Pleistocene ecosystem in the ice age lake bed at the Ziegler Reservoir (commonly referred to as the Snowmastodon site) put Snowmass Village prominently on the paleontological map of North America.

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.
