The geothermal areas of Yellowstone National Park include several geyser basins as well as other geothermal features such as hot springs, mud pots, and fumaroles. The number of thermal features in Yellowstone is estimated at 10,000. Although famous large geysers like Old Faithful are part of the total, most of Yellowstone's geysers are small, erupting to only a foot or two. The hydrothermal system that supplies the geysers with hot water sits within an ancient active caldera. Many of the thermal features in Yellowstone build up sinter, geyserite, or travertine deposits around and within them. Wikipedia
Kepler Cascades is a waterfall on the Firehole River in southwestern Yellowstone National Park. The cascades are located approximately 2.6 miles south of Old Faithful geyser. The cascades drop approximately 150 feet over multiple drops. The longest drop is 50 feet. The cascades are located very near to and visible from the Old Faithful to West Thumb road. Wikipedia
