The beach has the red tone I saw on a lot of these local beaches and that I suspect reflects the oxidized Devonian source for much of this material. There were steep eroding bluffs in both directions, exposing what appeared to be glacial drift (it doesn't look much like the drift we see on Puget Sound).
Northeast of Waterville, beyond the short stretch of bluffs, lies Inny Strand. Unlike Waterville, Inny is a spit with a well-developed set of dunes (and therefore a well-developed golf course). The golf course is protected from the sea by more riprap.
