Yellowstone National Park

Yellowstone National Park is the world's first national park, a site of amazing biological and geological diversity, and the site of a supervolcano that is still considered active. Part of the proceeds from sales of photos on this page will be donated to the non-profit Yellowstone Association, whose institute offers great classes on a variety of topics. For more Yellowstone photography, check out Dan Hartman's great site; his field notes to get an idea of what it's like to live in such a rich ecosystem.
