Geothermal Features

Yellowstone is an active volcano. Super heated water from the magma below the surface evidences itself as hot springs, fumeroles, geysers and mudpots. The colors of the waters, whether the reflected light from the sky or the thermophiles (micro-organisms capable of living in very hot water) show best on clear days at mid day. But the steam is best at daylight or sunset, as shown here along the Firehole Lake Road.
