Document Description
Project consists of conducting a geological study to extend the known history of the southern San Andreas fault's past behavior. The project will be conducted in two phases, both within the Salt Creek drainage. Phase 1 involves the excavation of a single 120' logn by 10-15' deep (fault perpedicular) trench to evaluate subsurface geological deposits for earthquake study. Phase 2 involves the excavation of two 200-250' long by 10-15' deep fault-parallel trenches, and a number of approx. 50' long fault perpendicular trenches, in order to trace offset beds across the fault. Sediment fencing, or other sediment control measures, will be employed to prevent any flow of sediment from the excavation sites into Salt Creek. All trenches will be refilled and landscaped when the study is complete. A State Parks archaeologist and paleontologist will be present during all excavations to assess and preserve any significant cultural or fossil resources unearthed.
