Absaroka Range
Template:Short description Template:Use mdy dates Template:Infobox mountain The Absaroka Range is a sub-range of the Rocky Mountains in the United States. The range stretches roughly north-south around Template:Cvt across the Montana–Wyoming border, and Template:Cvt at its widest east-west extent, forming both the eastern boundary of the Paradise Valley and Yellowstone National Park, and the western edge of the Bighorn Basin. The range borders the Beartooth Mountains to the east and north and the Wind River Range to the south and southwest. The northern edge of the range rests along I-90 and Livingston, Montana. The highest peak in the range is Francs Peak, located in Wyoming at Template:Cvt. There are 46 other peaks over Template:Cvt.
Geography
The range is drained by the Yellowstone River and various tributaries, including the Bighorn River.
Most of the range lies within protected lands including Yellowstone Park, the Absaroka-Beartooth Wilderness, North Absaroka Wilderness, Teton Wilderness, and Washakie Wilderness, spanning the Bridger-Teton National Forest, Custer National Forest, Gallatin National Forest, and Shoshone National Forest.
U.S. Highway 212 from Billings, Montana to Yellowstone climbs over Beartooth Pass Template:Convert in the neighboring Beartooth Mountains before winding through the Absarokas to the northeast gate of Yellowstone National Park. It is only open during the summer. U.S Route 14/16/20 follows the Shoshone River from Cody through the range to the eastern gate of the park.

History
The range is named after the Absaroka Native People.<ref name=gannett/> The name is derived from the Hidatsa name for the Crow people; it means "children of the large-beaked bird."<ref>Template:Cite book</ref> (In contrast, the Crow name, Awaxaawe Báaxxioo, means "Pointed Mountains [Like Sand Castles].")<ref name=LBHC/>
John Colter, who may have been the first white person to visit the area,<ref name="Harris1993"/> probably traveled along the foot of the Absarokas in 1807 during his reconnaissance of the Yellowstone region.<ref>Template:Cite book</ref> Early explorers also included Gustavus Cheyney Doane and Nathaniel P. Langford, who climbed the summit of Colter Peak in 1870.<ref>Template:Cite book</ref>
The proposed state of Absaroka shared the same age with the mountain range.<ref name=":4">Template:Cite web</ref><ref name=":0">Template:Cite web</ref> The USS Absaroka was named after this mountain range.
Geology
Geologically, the section of the range in Wyoming consists of volcanic breccia, whereas there is a transition to granite and gneiss bedrock further north of the state line.<ref>Template:Cite web</ref>
Absaroka Volcanic Province
Igneous rocks of the Absaroka Volcanic Province cover an area of approximately Template:Convert in southwestern Montana and northwestern Wyoming, including roughly one third of Yellowstone National Park. These extrusive rocks were erupted during the Eocene Epoch of the Paleogene Period. Radiometric dating has shown that eruptive activity lasted from about Template:Ma. The eroded remnants of many large stratovolcanoes are found in the area. The dissection of these long extinct volcanoes by erosion allows geologists to see volcanic structures that are impossible to see in active volcanoes. Many terms now widely used in volcanology originated in nineteenth century field studies of these ancient volcanoes.<ref>Template:Cite journal</ref>
