Jedediah Smith Wilderness

The Jedediah Smith Wilderness was designated because of the unique karst limestone features, including numerous caves and outstanding scenery. It was named after Jedediah Strong Smith, a well-educated and energetic mountain man from New York who explored the West in the early 1800's. Long and narrow, the Wilderness lies on the west slope of the Teton Range in western Wyoming and stretches from Yellowstone National Park south to Teton Pass. The Jedediah Smith Wilderness is part of the Greater Yellowstone Ecosystem and home to a variety of wildlife including black and grizzly bear, big horn sheep, wolverine, moose and elk. The Forest Service and Park Service are working together to return fire to the ecosystem.
