UPPER GEYSER BASIN
The Upper Geyser Basin in Yellowstone is one of the most amazing few acres on Earth because those few acres contain the greatest concentration of geysers, hot springs and other thermal features found in the world.
Thermal features are grouped together either by location or by their underground connections, or both. Below are the links to other areas in the Upper Geyser Basin. For ease of finding the thermal features, this site is divided by logical walking routes you’ll find when visiting the park.
