Riverside Geyser, Geyser in Upper Geyser Basin, Yellowstone National Park, Wyoming, US
Riverside Geyser sits on the bank of the Firehole River and shoots water in an arc that reaches about 75 feet into the air. The hot spray falls directly into the flowing river below.
The Hayden Geological Survey team documented this formation in 1871 while exploring Yellowstone and named it for its riverside location. The geyser has been one of the park's notable geothermal features ever since.
Scientists and researchers study the geyser's consistent eruption patterns to understand the complex underground systems that drive geothermal activity.
Eruptions happen roughly every five to seven hours, with each spray lasting about 20 minutes. Best to head down the trail toward it and wait at a safe viewing spot.
When the sun hits the erupting spray, rainbows form across the mist during certain times of day. This interplay of light and water creates a fleeting visual display that changes with weather and sun angle.

Geysers represent some of the most visible expressions of hydrothermal activity, occurring where underground water reservoirs are heated by magmatic sources. Yellowstone National Park in Wyoming holds more than half of the world's known geysers, including Old Faithful with its reliable eruptions...
