Amphitheater Mountain is a prominent 11,042-foot-elevation (3,366-meter) mountain summit located in Park County, Wyoming, United States.^[2]

Description

The peak is situated southwest of the town of Cooke City, Montana, at the northeast corner of Yellowstone National Park, two miles south of the park's Northeast Entrance Station. It is part of the Absaroka Range, and a portion of the mountain is within the North Absaroka Wilderness. Topographic relief is significant as the north aspect rises over 3,600 feet (1,100 meters) above Silver Gate in two miles. Volcanoes of the early Eocene supplied the material that formed the mountain 50–55 million years ago, and here created some of the most rugged terrain in Yellowstone Park.^[3] The mountain's name has been officially adopted by the United States Board on Geographic Names.^[2]

Climate

According to the Köppen climate classification system, Amphitheater Mountain is located in a subarctic climate zone with long, cold, snowy winters, and cool to warm summers.^[4] Temperatures can drop below −10 °F with wind chill factors below −30 °F. Precipitation runoff from the mountain drains into tributaries of the Lamar River.

The Absaroka Range is a sub-range of the Rocky Mountains in the United States. The range stretches about 150 mi (240 km) across the Montana–Wyoming border, and 75 mi (120 km) at its widest, forming the eastern boundary of Yellowstone National Park along Paradise Valley, and the western side of the Bighorn Basin. The range borders the Beartooth Mountains to the north and the Wind River Range to the south. The northern edge of the range rests along I-90 and Livingston, Montana. The highest peak in the range is Francs Peak, located in Wyoming at 13,153 ft (4,009 m). There are 46 other peaks over 12,000 ft (3,700 m).

Eagle Peak is a mountain in the Absaroka Range in the U.S. state of Wyoming and at 11,372 feet (3,466 m) is the highest point in Yellowstone National Park. It is located about 6 miles (9.7 km) east of the southeast arm of Yellowstone Lake.

Three Rivers Peak is a 9,958-foot (3,035 m) mountain summit in the southern section of the Gallatin Range in Yellowstone National Park, in the U.S. state of Wyoming.

Amethyst Mountain, el. 9,609 feet (2,929 m) is the highest peak and central part of a northwest – southeast trending ridge that lies between the Lamar River to the northeast and Deep Creek to the southwest within Park County, Wyoming. From northwest to southeast, this ridge consists of Specimen Ridge, Amethyst Mountain, and the Mirror Plateau in Yellowstone National Park. The nearest town is Silver Gate, Montana, which is 19.2 miles away.

Donoho Peak is a 6,696-foot-elevation mountain summit located in the Wrangell Mountains, in the U.S. state of Alaska. The peak is situated in Wrangell-St. Elias National Park and Preserve, 6 mi (10 km) north-northwest of Kennecott, and 9 mi (14 km) north of McCarthy, at the confluence of the Kennicott Glacier and Root Glacier. The peak's name was reported in 1931 by the United States Geological Survey. The mountain lies within the Copper River drainage basin. Bears frequent the Donoho Peak and Donoho Lakes area. An ascent of the mountain involves 14 miles round-trip from Kennecott to the summit, including crossing the Root Glacier and gully scramble via the south aspect of the mountain. Ruins of the Regal Mine remain at an elevation of 5,440 feet on the south slope of the mountain. Only small amounts of copper ore were ever produced, however. On a clear day the summit of Donoho Peak offers views of Mount Blackburn to the northwest and the Stairway Icefall on Regal Mountain to the north-northeast.

Avalanche Peak is a 10,568-foot (3,221 m) summit located on the shared border of Yellowstone National Park and North Absaroka Wilderness, in Park County, Wyoming. It is part of the Absaroka Range.

Clyde Peak is an 8,610-foot-elevation (2,620-meter) mountain summit located in Glacier National Park in the U.S. state of Montana. The mountain straddles the border shared by Flathead County and Glacier County. It is situated on the Continental Divide so precipitation runoff from the west side of the mountain drains into Thompson Creek which is part of the Middle Fork Flathead River watershed, and the east side drains into headwaters of Red Eagle Creek, which flows to Red Eagle Lake, thence Saint Mary Lake. It is set in the Lewis Range, and the nearest higher neighbor is Mount Logan 1.44 mile to the northwest. Topographic relief is significant as the southwest aspect rises approximately 4,000 feet in one mile.

Citadel Peaks is a mountain ridge located in the Goat Haunt area of Glacier National Park, in Glacier County of the U.S. state of Montana. This arête with a row of sharp points is part of the Livingston Range, and is approximately four miles east of the Continental Divide. Neighbors include Olson Mountain, two miles (3.2 km) to the north, Mount Cleveland four miles (6.4 km) to the east, and Kootenai Peak 2.7 miles (4.3 km) to the south. Topographic relief is significant as Citadel Peaks rises over 3,800 feet above Waterton Lake in less than two miles, and 3,000 feet above Lake Janet in one mile. Precipitation runoff from the mountain drains to the south end of Waterton Lake. The first ascent of Citadel Spire, a major pinnacle on the ridge, was made in 1967 by Jerry Kanzler, Jim Kanzler, Ray Martin, and Clare Pogreba. This geographical feature's name was officially adopted in 1929 by the United States Board on Geographic Names. To the Pikuni people, Citadel Peaks is known as "Ataniawxis", meaning "The Needles".

Porcupine Ridge is a prominent mountain ridge located in the Goat Haunt area of Glacier National Park, in Glacier County of the U.S. state of Montana. This mountain is part of the Livingston Range, and is situated 1.5 mile east of the Continental Divide. Topographic relief is significant as the summit rises approximately 3,900 feet above Lake Frances in one mile, and nearly 5,000 feet above Waterton Lake in five miles. Precipitation runoff from the mountain drains to the Waterton River via Olson and Valentine Creeks. This geographical feature's name was officially adopted in 1911 by the United States Board on Geographic Names.
