Clepsydra Geyser Seen From Fountain Paint Pot Trail, Yellowstone National Park

"This nearly constant performer splashes from several vents and its steam can be seen throughout the Lower Geyser Basin. Its name is Greek for water clock, and was given because the geyser used to erupt regularly every three minutes. Since the 1959 Hebgen earthquake, however, Clepsydra erupts almost without pause."

Bison - And Human - Footprints Around Crested Pool, Yellowstone National Park

"With temperatures that average temperate of 191.1°F (88.4°C), Crested Pool is almost constantly boiling, sometimes to 6 feet (2 m) or more. The extreme heat prevents most bacterial growth, resulting in exceptionally clear blue water. Boiling is particularly active along the intricate sinter formation circling the spring, the “crested” edge. Listen for the sizzling. Crested Pool has an average pH of 8.9 and an average conductivity of 2269 uS/cm."

Winter Landscape Around Giant Geyser, Yellowstone National Park

Winter in Yellowstone is a magical season and presents yet another side of this park's personality. "Giant Geyser became dormant in 1955. Since then, it has slowly become active and erratic. During 2007, it erupted more than 50 times. During 2010, it erupted once. Its spectacular eruptions last more than an hour and can reach 250 feet (76 m). Before and during eruptions, small geysers on the same platform may erupt."
