Lichen polygons. Green River Lakes, Wind River Range, Bridger-Teton National Forest, Rocky Mountains, Wyoming, USA. The Continental Divide follows the crest of the "Winds". Mostly composed of granite batholiths formed deep within the earth over 1 billion years ago, the Wind River Range is one of the oldest mountain ranges in North America. These granite monoliths were uplifted, exposed by erosion, then carved by glaciers 500,000 years ago to form cirques and U-shaped valleys. Glaciers scoured the terminal moraine which naturally dams the Green River Lakes, the headwaters of the Green River (chief tributary to the Colorado River).Add to Cart Add to Lightbox Download
