Geo 730: May 23, Day 509: The View Southwest

Looking southwest from Bandon's south jetty, you can see the numerous sea stacks that are so characteristic of Oregon's southern coast. The rock unit here is Otter Point Formation, a highly variable and highly faulted melange. The combination of rock variability- from poorly consolidated graywacke and serpentinite to very tough blueschist- and abrupt transitions between them along with fracturing due to faulting results in extremes of differential weathering and erosion. The end product is a grand coastline that is as nice as any I've seen elsewhere.
