Geo 365: Dec. 19, Day 353: Arch Rock 1

If you've looked at the FlashEarth location for the last couple of days, you can see the promontory at Arch Rock has a significant north-south extent. This and the last two photos were taken at a viewpoint near the south end of the headland. This is supposedly the largest arch on the Oregon coast, and I know I haven't seen a larger one anywhere. If you look carefully, you can see the shearing and faulting that weakened the edges of the arch.
