Wave Spring 照片檔

A wide-angle view of a steaming hot spring known as Wave Spring at Upper Geyser Basin in Yellowstone National Park. The water is a clear dark green surrounded by bacterial mats and patches of beige bare ground. There is a snow-covered small hill in the background wtih trees and rocks. The sky is a matte gray-white with some clouds. There is a small plaque with the name of the hot spring at the center foreground of the image.
