Union Mountain is a 7,601-foot (2,317-metre) summit located in Flathead County of the U.S. state of Montana.^[2]

Description

Union Mountain is located in the Flathead Range, a subset of the Rocky Mountains. It is situated in the Great Bear Wilderness, on land managed by Flathead National Forest. Schafer Meadows, Shafer Ranger Station, and the Schafer landing strip are set below the mountain's northeast base. The landing strip was grandfathered with the wilderness designation. The landing strip provides access for hikers, hunters, and river rafters. Precipitation runoff from the mountain drains north to the Middle Fork Flathead River, and topographic relief is significant as the summit rises 2,800 feet (850 meters) above the river in approximately 1.5 mile. The nearest higher neighbor is Capitol Mountain, 1.9 miles (3.1 km) to the west-southwest.

Climate

Based on the Köppen climate classification, Union Mountain is located in a subarctic climate zone characterized by long, usually very cold winters, and short, cool to mild summers.^[3] Winter temperatures can drop below −10 °F with wind chill factors below −30 °F.

Geology

Union Mountain is composed of sedimentary rock laid down during the Precambrian to Jurassic periods. Formed in shallow seas, this sedimentary rock was initially uplifted beginning 170 million years ago when the Lewis Overthrust fault pushed an enormous slab of precambrian rocks 3 mi (4.8 km) thick, 50 miles (80 km) wide and 160 miles (260 km) long over younger rock of the cretaceous period.^[4]

Stanton Mountain is a 7,750 feet (2,360 m) mountain summit located in the Livingston Range, of Glacier National Park in the U.S. state of Montana. Stanton Mountain rises more than 4,500 feet (1,400 m) above the northern shore of Lake McDonald. The mountain's name refers to Mrs. Lottie Stanton who lived near the west side of the park in the late 1800s, and with her husband operated a livery stable in historic Demersville. She was a pioneering woman who followed the construction camps during the railroad building days. The mountain's name was officially adopted in 1929. In the late 1800s it was known as Mt. Lottie Stanton. The nearest higher peak is Mount Vaught, 1.38 miles (2.22 km) to the northeast. Precipitation runoff from the mountain drains into tributaries of the Flathead River.

Calf Robe Mountain is a 7,948-foot-elevation (2,423-meter) mountain summit located in Glacier National Park in the U.S. state of Montana. It is situated on the Continental Divide in the Lewis Range, and can be seen from Highway 2 midway between Marias Pass and East Glacier Park. The summit is set on the border shared by Flathead County and Glacier County. Topographic relief is significant as the east aspect rises 2,500 feet in one mile. The immediate area between the mountain and highway is known for its aspen and beaver dams.

Red Crow Mountain is a 7,891-foot-elevation (2,405-meter) mountain summit located in Glacier National Park in the U.S. state of Montana. The summit is set on the border shared by Flathead County and Glacier County. It is situated on the Continental Divide so precipitation runoff from the east side of the mountain drains into Railroad Creek which is part of the Two Medicine River watershed, and the west side drains to Ole Creek, which is a tributary of Middle Fork Flathead River. It is set in the Lewis Range, 6.5 miles southwest of East Glacier Park Village. Topographic relief is significant as the east aspect rises approximately 2,000 feet in one mile. The nearest higher neighbor is Calf Robe Mountain 1.2 mile to the southeast, with Firebrand Pass forming the saddle between these two peaks.

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.

Precipitation runoff from the mountain drains into tributaries of Cut Bank Creek and Two Medicine River, which merge to form the Marias River. Topographic relief is significant as the south aspect rises nearly 3,000 feet above Lower Two Medicine Lake in two miles. The mountain's name was officially adopted in 1929 by the United States Board on Geographic Names.
