help Riverside Geyser FAQ

Where is Riverside Geyser located within Yellowstone National Park?

Riverside Geyser is a prominent cone geyser situated in the Upper Geyser Basin of Yellowstone National Park. It rests directly on the bank of the Firehole River, offering viewers a highly picturesque setting. It is easily accessible via the paved trail system near the Old Faithful area.

How often does Riverside Geyser erupt?

This geyser is highly predictable, typically erupting roughly every 5.5 to 6 hours. Each spectacular eruption lasts about 20 minutes, featuring a characteristic 75-foot arch of water shooting over the Firehole River. Ranger stations in the basin often post estimated eruption times for visitors.

When was Riverside Geyser first discovered and named?

The geyser was officially named in 1871 during the Hayden Geological Survey, which was the first federally funded survey of the Yellowstone region. It earned its simple name due to its immediate proximity to the Firehole River.

What makes Riverside Geyser's shape unique compared to Old Faithful?

Unlike the straight-up water plume of Old Faithful, Riverside Geyser erupts at a distinct angle from a sinter cone, creating a massive 75-foot arch over the river. Its extended 20-minute eruption duration also provides much longer viewing opportunities for park visitors and photographers.
