Absaroka Range Flyover, WY

The Absaroka Range is a sub-range of the Rocky Mountains in the United States. The range stretches about 150 mi across the Montana–Wyoming border, and 75 mi at its widest, forming the eastern boundary of Yellowstone National Park along Paradise Valley, and the western side of the Bighorn Basin.

The Absaroka Mountain Range is the remnant of a large volcanic field that was active for 10 million years during the Middle Eocene, 53-43 million years ago,. Volcanic activity occurred along two subparallel trends that extended 165 miles in length, from Livingston, MT to Dubois, WY. The field is 60 miles wide from Buffalo Bill Dam to Lake Butte Overlook in the eastern quarter of Yellowstone National Park. The North Fork highway (US 14-16-20) travels through this extinct volcanic field. Twelve volcanic centers generated volcanos that rose up to 10,000 feet above the valley floors. The rocks deposited from these volcanos comprise the Absaroka Volcanic Supergroup. The volcanic, and volcanic derived sedimentary rocks (volcaniclastic), cover an area of 9,000 square miles and reach a maximum thickness of 5,000 feet. The total volume of material exceeds 7,000 cubic miles, with sixty percent of the volume erupted in a two million years window (49-47 million years ago).​
