Rock pattern on the Oregon coast: Natural geological abstract image from the colours and sediments of soft rock on the beach near Yachats on the Oregon Coast, U.S.A. (1)

This post features photographs of the natural geological abstract images to be found in the soft sedimentary rocks that overlie the hard volcanic rocks on the beach near Yachats on the Oregon Coast in the U.S.A. Both types of rock have been affected by wave action and weathering. The massive volcanic rocks have resisted erosion and largely remain with minimal change. On the other hand, their original covering of softer more superficial deposits has been gradually removed and is now visible only at the top of the beach beneath the overhanging shoreline vegetation.

These soft deposits show bright rusty colours and intricate layered patterns that could be viewed as nature’s own abstract art.  They are evidence for the complex natural geological mechanisms that contrive to build up and break down the coastline of the American North-West.
