Note - please be prepared to car pool - at least four people/car. Cars may be parked for the day at USGS
We will be hiking around for a while (>1 hour), so appropriate footwear is essential, as are a hat, water, and sun screen.
We will go off trail, so long pants are strongly advised, especially for people sensitive to poison oak - people may want to bring poison oak avoidance products.
Gaitors are recommended - the grasses are full of clingy seeds and foxtails that will drive you crazy.
There are ticks and/or mosquitos in abundance, concerned folks might want to bring repellent.
People should bring a daypack for water and lunch.

This field trip is intended to highlight the Holocene active San Andreas Fault along the San Francisco Peninsula, in particular with respect to the 1906 San Francisco earthquake. Stops will be along the fault where the active trace is clearly visible in the geomorphology as well as in the urban corridor south of San Francisco where development has obscured the precise location of the fault trace. Topics of discussion will include 1906 surface rupture, seismic hazard, and new mapping using historical data to help refine the locations of the 1906 rupture through the urbanized section of the fault.
