A moderately large quake (5.9) hit on the Antelope Valley Fault somewhere in the desert below the east side of the Sierra today. But rockfall over roads has occurred as far north as South Lake Tahoe. Hwy 395 was temporarily closed near Coleville for cleanup. That's near where the road over Monitor Pass intersects. But there could be issues on other mtn roads, so best to check in advance before heading that way soon. Lots of serious aftershocks so far.
