description Deluge Geyser Overview
Deluge Geyser is a hydrothermal feature in the Upper Group of Yellowstone National Park's remote Heart Lake Geyser Basin. The basin lies along Witch Creek near the western shore of Heart Lake and contains several groups of geysers, hot springs, and other thermal features. Deluge is described as an irregular basin with bluish-gray water and rosette-shaped sinter around its edge; unlike the developed geyser areas, Heart Lake is a backcountry destination reached by trail.
