The Boulder Mountains are a mountain range running roughly north to south located west of Boulder between Helena and Butte in the U.S. state of Montana. [1] Parts of the range are in four different counties: Deer Lodge, Jefferson, Lewis and Clark, and Silver Bow. [1]
Haystack Mountain, which reaches 8,819 feet (2,688 m), is the tallest peak in the range. [2] [3] The three other highest peaks are Jack Mountain at 8,752 feet (2,668 m), Bull Mountain at 8,609 feet (2,624 m), and Thunderbolt Mountain at 8,597 feet (2,620 m). [2] All four peaks are in Jefferson County. [2]
Rocker Peak, 8,455 ft (2,577 m), [4] is near Jack Mountain (Montana), the second highest peak in the Boulder Mountains. [5] There is a SNOTEL weather station near the summit of Rocker Peak at an elevation of 8,000 ft (2,438 m). Rocker Peak has a subalpine climate (Köppen Dfc), bordering on an Alpine climate (Köppen ET).

The Big Snowy Mountains are a small mountain range south of Lewistown in Fergus County, Montana. Considerably east of and isolated from the main crest of the Northern Rockies, they are one of the few points of significant elevation in the immediate area and are considered one of Montana's island ranges. The range's highest elevation is 8,681 feet (2,646 m). The smaller Little Snowy Mountains are a contiguous range immediately to the east.
Boulder Peak is located in the Livingston Range, Glacier National Park in the U.S. state of Montana. The remnant Boulder Glacier is situated on the northern slopes of the mountain.
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 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. 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
