These ranges are completely distinct geologically speaking with the Absarokas composed primarily of volcanic and metamorphic rock, while the Beartooths are made up almost entirely of granitic rocks. The Absarokas are noted for their dark and craggy appearance, lush and heavily forested valleys and abundant wildlife. The highest peak in the range, located in Wyoming, is Francs Peak at 13,153 feet (4,009 m). The Beartooths are more alpine with huge treeless plateaus and the highest peak in the state of Montana.
