Yellowstone Geysers Wiki

Welcome to the 

Yellowstone National Park (Wyoming, USA) contains the highest concentration of active thermal features in the world, including thousands of hot springs, boiling mud pots, fumeroles, and approximately 300-500 geysers. It is home to half of the world's total number of geysers in its nine geyser basins.

While some geysers, like the well-known Old Faithful, are highly predictable, others are much more sporadic. It is our goal to catalog characteristics and provide information for tourists, geyser enthusiasts, and researchers on the geysers and other thermal features found in Yellowstone.
