Firehole River
Significant geyser basin
Geothermal surrounds
Water temperature increase
The Firehole River is conceivably the most peculiar waterway in the world. Streaming through three large active geyser basins, complete with mud pots and hot springs, the outflow from these thermal features discharges directly into the main current.
“We shall never know and name all the hot springs and geysers of this wonderland, but we may become acquainted with the voice of a stream and know it as the speech of a friend.” – Orange Perry Barnes
