Yellowstone's Upper Geyser Basin

The Upper Geyser Basin is the most unique two square miles on the Earth. It’s home to not only Old Faithful, but nearly a quarter of the world’s geysers. Geyser Watch divides this area up into seven sections that follow the usual pattern of foot traffic as people visit this amazing place.

This part of Yellowstone Naturalist is under construction. Check back later and more areas will be available.
