Don't make any plans for a drive up Cedar Canyon anytime soon. This is going to take months to fix.
I took these photos last Monday--two days after the landslide occurred early Saturday Morning. The right flank of the slide is where a massive rock fall covered the road a couple of years ago (old post about 2009 rock fall). A similar landslide took out this road back in, I believe, 1991. A significant storm with lingering rain likely triggered the slide.
