Positioned along the bank of the
Firehole River, Riverside Geyser is one of the most picturesque geysers in
Yellowstone. A 75 foot column of water arches gracefully over the
river during its 20-minute eruption. Eruptions are about 5.5 to 6.5 hours
apart. When water starts to run over the edge of Riverside Geyser's
cone, it's an indication that the geyser will erupt within the next couple
of hours. |
