Edna Fault is a 584-foot (178m) strike-slip fault in Edna Valley, California, known for its abrupt right angle shape when viewed from the north or south. Its cliff face faces east.

Geology[edit]

Edna Fault is part of the San Luis (Mount Buchon) range in San Luis Obispo County, California. It contains both Miocene and Pliocene strata against a Franciscan basement and forms the northern border of the Pismo syncline.[3] According to trenching and bedrock mapping studies, the fault was inactive during the late Quaternary period.[3][4]

Wildlife[edit]

Known flora and fauna of Edna Fault includes red-tailed hawk, ground squirrels, bobcats, and coast live oaks,[citation needed] among others.

Land use[edit]

Though many local residents have expressed interest in hiking or climbing the fault[citation needed], the property is under private ownership and such activities are uncommon.

A single road owned by PG&E leads up behind the fault nearly to the edge.
