Shore Acres
Looking south at some of the impressive geology of Shore Acres.
Located on the south coast of Oregon near Coos Bay, Shore Acres contains some of the most dramatic geology on the West Coast. Layers of sediment tilt at steep angles, some are spatter with dark round rock formations like cannon balls, and the surf hitting the rocks shoots spectacular waves 50 feet into the air.
The rock formations that look like cannon balls are called concretions, compact masses of mineral matter embedded in a host rock, mostly sandstone.
