San Andreas Fault

San Andreas Fault On the north side of the San Gabriel Mountains, the San Andreas Fault forms a nearly linear, relatively simple break, slightly concave to the south (fig. 3 of Matti and others, 1992a). Within Lone Pine Valley, the San Andreas forms a linear "rift valley" that reflects long-term activity on the fault. This trace of the fault along the north flank of the San Gabriel Mountains represents the Mojave Desert segment of the San Andreas (Barrows, 1975, 1979, 1980, 1987; Barrows and others, 1976, 1985, 1987); to the southeast, the Mojave Desert segment passes into the San Bernardino strand that lies along the base of the San Bernardino Mountains. For more detail, see the discussion of the San Andreas Fault zone in the San Gabriel Mountains by Matti and others (1992a).
