Crystal Geyser

Crystal Geyser is located on the east bank of the Green River approximately 4.5 miles (7.25 km) downstream from Green River, Utah. It is a rare example of a cold water carbon dioxide driven geyser; geothermal activity does not play a role in the activity of the geyser. The ground water near the geyser has significant quantities of dissolved carbon dioxide, along with substantial...

Lithops Stone Plants

Lithops,(commonly called "flowering stones" or "living stones") are true mimicry plants: their shape, size and color causes them to resemble small stones in their natural surroundings. The plants blend in among the stones as a means of protection. Grazing animals which would otherwise eat them during periods of drought to obtain moisture usually overlook them. Even experts...
