The waters of Pine Creek cut through a high mountain meadow below the scree slopes of Cathedral Peak in the Maroon Bells -Snowmass Wilderness Area near Aspen, Colorado, USA. The cooler autumn weather has turned the alpine willow shrubs and grasses a golden yellow.
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.
