Looking toward South Mount Hawkins in the West Fork San Gabriel Canyon from State 39. This road was planned to be improved but landslides prevented this work from being completed. In the case of this area, almost all of the low lying areas not covered in snow are landslides in one form or another. Even Crystal Lake, where this roadway is headed, exists because of landslides.

New Page – Southern California Passes

This one, while small, was felt over a wide area. If you are among the many that did feel it, the USGS wants to hear from you! These “Did You Feel It?” reports help them to understand earthquakes further.
