One of the truly amazing and simultaneously terrifying sites is to see an aerial view of Elkhorn Scarp, a visual scar on the landscape of central California that shows the San Andreas Fault's mark on the land. And according to newly discovered “mud pots”, the San Andreas fault may be longer than previously thought.
A mudpot is simply a hot spring of bubbling mud that speaks to geothermal activity in the rocks beneath it, which has pushed water or gas up through the ground. These mudpots were found by David Lynch and Kenneth Hudnut of the US Geological Survey, who were part of a comprehensive analysis of a region lying well beyond what was believed to be the southernmost point of the San Andreas Fault line.
