Old Baldy is a 9,156-foot (2,791-metre) double summit mountain located in Teton County of the U.S. state of Montana.^[1]

Description

The west summit is slightly higher than the 9,150-foot east summit, and approximately 1,000 feet distance separates the two.^[2] Old Baldy is located along the Rocky Mountain Front, which is a subset of the Rocky Mountains. It is situated 11 miles east of the Continental Divide, in the Bob Marshall Wilderness, on land managed by Lewis and Clark National Forest. The nearest town is Choteau, 29 miles to the east, and nearest access is the South Fork Teton Road 109. Precipitation runoff from the east side of the mountain drains into headwaters of South Fork Teton River, and the west side drains into tributaries of the North Fork Sun River. Topographic relief is significant as the east aspect rises 3,350 feet (1,020 meters) above South Fork Teton River in two miles. The Old Baldy name was officially adopted by the United States Board on Geographic Names on December 31, 1959.^[1]

Geology

Old Baldy is composed of sedimentary rock laid down during the Precambrian to Jurassic periods. Formed in shallow seas, this sedimentary rock was pushed east and over the top of younger rock during the Laramide orogeny.^[4] The Lewis Overthrust extends over 280 miles (450 km) from Mount Kidd in Alberta, south to Steamboat Mountain which is located 40 miles south of Old Baldy, which places Old Baldy within the southern extent of the Lewis Overthrust.^[5]

Climate

Based on the Köppen climate classification, Old Baldy is located in a subarctic climate zone characterized by long, usually very cold winters, and mild to warm summers.^[6] Winter temperatures can drop below −10 °F with wind chill factors below −30 °F.

Rocky Mountain (Montana) is a nearby peak to the south of Old Baldy. There is no weather station, but this climate table contains interpolated data.

Mount Cleveland is the highest mountain in Glacier National Park, located in Montana, United States. It is also the highest point in the Lewis Range, which spans part of the northern portion of the park and extends into Canada. It is located approximately 3 mi (4.8 km) southeast of the southern end of Waterton Lake, and approximately 5 mi (8.0 km) south of the US–Canada border. The east side of the future national park was purchased by the federal government from the Blackfoot Confederacy in 1895 during the second term of President Grover Cleveland. According to the United States Board on Geographic Names, the mountain is named for the former president.
