Week 2 Big Sur Igneous Rocks

I visited the amazing Big Sur costline, and the famous "keyhole" rock at Pfeiffer Beach in the park. The beach has the typical well-sorted sedimentary rocks that are expected at the beach, but most of the coastline is dominated by bold cliffs of igneous rocks, which were formed when molten rock cooled beneath the surface. Over time, the erosive forces of wind and the ocean have worn away much of the surrounding shale and clay, leaving just the striking igneous rock behind.
