Geyser
Yellowstone is the largest geyser locale, containing thousands of hot springs, and approximately 300 to 500 geysers. It is home to half of the world's total number of geysers in its nine geyser basins. It is located mostly in Wyoming, USA, with small portions in Montana and Idaho. Yellowstone includes the world's tallest active geyser (Steamboat Geyser in Norris Geyser Basin), as well as the renowned Old Faithful Geyser, Beehive Geyser, Giantess Geyser, Lion Geyser, Plume Geyser, Aurum Geyser, Castle Geyser, Sawmill Geyser, Grand Geyser, Oblong Geyser, Giant Geyser, Daisy Geyser, Grotto Geyser, the Fan & Mortar Geysers, & the Riverside Geyser, all in the Upper Geyser Basin which alone contains nearly 180 geysers.
Fountain Paint Pot
Several significant geysers erupt near the Paint Pots, notably Fountain Geyser, which usually has several large eruptions a day; Clepsydra Geyser, which is active most of the time except following an eruption of Fountain; and powerful but erratic Morning Geyser, active in the latter part of 2018 following a dormancy of nearly five years. These features and others are reachable by a short boardwalk trail from the parking lot on the main road through Lower Geyser Basin. Off-trail travel in this area is prohibited due to hazardous conditions.
