Step 1: Locate Garlock fault alignment
Step 2: Review alignment transfered to overlays
Step 3: Locate eastern end of fault.
By word of mouth and small scale maps the eastern end of the fault appears to be located just west of Salt Springs, which is on state highway 127 between Baker and Shoshone, California near Dumont Dunes.
