Trona Tufa Pinnacles Natural Area The Trona Pinnacles are spectacular crags of calcareous
tufa rising to a height of 30 meters (100 feet) and are perhaps the most
impressive example of tufa formations on the continent.
While it has been suggested that their formation is the result of
hot-springs activity, the most generally accepted explanation is that they were
formed by calcium carbonate precipitates in the Pleistocene Searles Lake.
When the lake dried, the spires were formed by the subsequent erosion of
the surrounding softer material. In
many places the tufa merely coated the rock, but here it formed thick, knobby
deposits. The pinnacles rise from the floor of the now dry Searles
Lake. Integrity: The
area is now protected, though some of the tufa in the vicinity has been gathered
for sale. Use: Research,
educational, observational. December 1976
