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.
Crazy Peak, elevation 11,214 ft (3,418 m), is the highest peak in the Crazy Mountains, an island range of the Montana Rockies, in the United States.

Crazy Peak is also the most topographically prominent peak in Montana. A small glacier exists on the northeast slope of the mountain. The mountain is located on private land within the Gallatin National Forest.
