Travertine Hot Springs, Lower Pools
Bridgeport, CA - August 2004

This image shows an active travertine ridge, built over millennia by travertine
 deposition from mineral-rich artesian hot spring water flowing down the spine of
the ridge.  The area around the springs is now a protected reserve, and the
soaking pools at the foot of the ridge were constructed
 and are maintained by volunteers.
