Yellowstone is a world-class site for both wildlife and geological features. The National Park preserves the heart of the Yellowstone Country in Wyoming, but the effects of the great Yellowstone volcanic system extend across Idaho and on into Montana. My home in Idaho Falls lies along the track of former eruptive sites of the Yellowstone Hots Spot in the Snake River Plain. Island Park is part of the current complex of three calderas that make up the Yellowstone Supervolcano. Many of my best photos and favorite memories originate in the Greater Yellowstone Region, and I hope to share them with as many people as possible.
