Geo 730: April 11, Day 467: Sunken Grade

After departing Agate Beach, we drove north past Beverly Beach and Otter Crest. I believe this road... disruption... was just before the pullout to Beverly Beach. It's a bit counter-intuitive; we're facing north, so the ocean is to our left, but the slump movement was clearly to the right. I'm pretty sure what happened here was the result of erosion in a stream off to the right, hidden in this perspective. Coast range sediments in this area weather quickly in our mild, moist climate, and mass movements of various kinds- slumps, slides, rock falls and debris flows- are common. Most of the time, though, they're not quite as in-your-face as this one.
