" Thermal Snow " ____ 9775Lh
Travertine terraces are covered with snow and mountaintops reflected in the steaming pools at Mammoth Hot Springs.
This is a rare image due to ever changing character of these terraces and pools. Thermal pools will seemingly 'dry up' ... then reappear elsewhere. In this area groundwater continually emerges at 163ºF (73°C). Recent studies indicate travertine growth was approximately 1 to 2 feet (0.3 - 0.6 meters) in a 10-month period.
