From the Bureau of Land Management:
Wonderful early-autumn picture of the Centennial mountain range in Montana. The area is a Wilderness Study Area that spans much of this east-west range. The Centennials serve as a connection between Yellowstone and the Northern Rockies for grizzlies and other wildlife to migrate.

In the shadow of 13,063-foot Wheeler Peak, 5,000 year old bristlecone pine trees grow on rocky glacial moraines. Come to Great Basin National Park to experience the solitude of the desert, the smell of sagebrush after a thunderstorm, the darkest of night skies, and the beauty of Lehman Caves. Far from a wasteland, the Great Basin is a diverse region that awaits your discovery.
