San Andreas Fault at Mile High

Click the photo for the full-size version. The cluster of trees marks Caldwell Lake, which lies on the fault trace and is probably a sag pond. The notch on the horizon is where the fault passes to the east; the roadway at left points toward where the previous photo was taken. The high peak at left is Table Mountain near Wrightwood, on the North American plate; the range on the right is part of the San Gabriel Mountains, on the Pacific plate.
