Haystack Butte is a 7,486-foot-elevation (2,282-meter) summit located in the Lewis Range, of Glacier National Park in the U.S. state of Montana. It is situated one mile west of the Continental Divide, in Flathead County, above the Weeping Wall on its south slope. Topographic relief is significant as the west aspect rises 3,900 feet (1,200 meters) above McDonald Creek in less than 1.5 mile. It can be seen from Logan Pass, and from Going-to-the-Sun Road which traverses the west and south slopes of the peak. The nearest higher neighbor is Mount Gould, 1.07 miles (1.72 km) to the northeast.[1] Climbing access is via the Highline Trail. This geographical feature's descriptive name was on maps as early as 1904, and was officially adopted March 6, 1929, by the United States Board on Geographic Names[3]

Climate

Based on the Köppen climate classification, Haystack Butte is located in an alpine 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 peak drains into McDonald Creek, thence Lake McDonald.

Geology

Like other mountains in Glacier National Park, Haystack Butte Tail 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.[5] The bulk of the peak is composed of limestone of the Siyeh Formation, with a diorite cap.[6]
