Absaroka–Beartooth Wilderness was created from existing National Forest lands in 1978 and is located in Montana and Wyoming, United States. The wilderness encompasses two distinct mountain ranges: the Beartooth and Absaroka ranges. These ranges are completely distinct geologically speaking, with the Absaroka composed primarily of volcanic and metamorphic rock, while the Beartooth is made up almost entirely of granitic rocks. The Absaroka are noted for their dark and craggy appearance, lush and heavily forested valleys, and abundant wildlife. The highest peak in the range, in Wyoming, is Francs Peak at 13,153 feet (4,009 m). The Beartooth is more alpine, with huge treeless plateaus and the highest peak of Montana. The wilderness has more than 120 peaks over 10,000 feet (3,000 m) and 28 peaks over 12,000 feet (3,700 m), including Montana's highest, Granite Peak at 12,799 feet (3,901 m). The wilderness is integral to the 20-million-acre (81,000 km2) Greater Yellowstone Ecosystem and borders Yellowstone National Park.

Cloud Peak Glacier is in the Bighorn Mountains in the northcentral section of the U.S. state of Wyoming. Centered within the Cloud Peak Wilderness of Bighorn National Forest, Cloud Peak Glacier is the only active glacier in the Bighorn Mountains.

Black Tooth Mountain is located in the Bighorn Mountains in the U.S. state of Wyoming. The peak is the second highest in the range after Cloud Peak, which is only 1.5 miles (2.4 km) to the south, and the summit is located in the Cloud Peak Wilderness of Bighorn National Forest. The sharp dark profile of the mountain resembles a dark tooth or fang, hence the name. Because of the steep terrain, Black Tooth Mountain is one of the hardest mountains to climb in the Bighorns. Many of the trails up the mountain are unmarked which adds to the difficulty of reaching the summit. Mount Woolsey is an adjacent summit only .20 mi (0.32 km) to the southeast. Another high peak of the Bighorns known as Hallelujah Peak is situated along a knife-like ridge known as an arête .64 mi (1.03 km) to the northeast. Several tiny remnant glaciers can be found on the north slopes of Black Tooth Mountain.
Mount Woolsey is located in the Bighorn Mountains in the U.S. state of Wyoming. The peak is the third highest in the range after Cloud Peak, which is only 1.3 miles (2.1 km) to the south, and the summit is located in the Cloud Peak Wilderness of Bighorn National Forest. Black Tooth Mountain, the second highest mountain in the Bighorns, is an adjacent summit only .20 mi (0.32 km) to the northwest. Mount Woolsey is on a knife-like ridge known as an arête and is connected to both Black Tooth Mountain and Cloud Peak by this ridge. Along the arête is another mountain peak known as The Innominate. A small glacier lies below the arête to the southeast of Mount Woolsey.
Hallelujah Peak, also known as Peak 12590, is located in the Bighorn Mountains in the U.S. state of Wyoming.
