Yellow-Legged Frog
Since 2010, scientists at the various agencies including the USGS and FWS have worked to reintroduce an endangered frog species, the Yellow-Legged Frog, back into it's native habitat in Southern California. USGS scientists found this particular adult mountain yellow-legged frog on June 10, 2010 in Tahquitz Creek in the San Jacinto Wilderness, San Bernardino National Forest, California.
