High Quality Content by WIKIPEDIA articles! The Absaroka Range is a sub-range of the Rocky Mountains in the United States. The range stretches about 150 mi (240 km) across the Montana-Wyoming border, forming the eastern boundary of Yellowstone National Park and the western side of the Big Horn Basin. The range borders the Beartooth Mountains to the north and the Wind River Range to the south. The highest peak in the range is Francs Peak at 13153 ft (4009 m). There are 46 other peaks over 12000 ft (3700 m). The range is named after the Absaroka Indians. The name is derived from the Hidatsa name for the Crow people; it means "children of the large-beaked bird."
