Runoff waters from recent rains in Colorado's Rocky Mountain National Park, cascade over a rocky ledge at Granite Pass. Grasses, burned by recent frosts, turn brown as shrubs begin to brighten with their autumn colors. Towards the west, the rugard skyline of the USA's continental divide rises above the valley floor.
Passing clouds cast their shadows over peaks of the Grand Teton Ranges that arise abruptly and dramatically from sagebrush covered river flats near Jackson, Wyoming, USA. Grand Teton at 3,770 feet, (4,200 m), towers about 7,000 feet, (2130 m), above the valley floor.
Sunlight filters through breaks in the clouds as an intense rain shower buckets down into the headwaters of Bear Creek in the Mount Evans Wilderness area near Denver, Colorado.
