Looks like a place that should be on my list to see. The rock (is > that basalt?) shelving/layering appears to have interesting geology.

Unraveling the geology of the floods radically changed thinking about how the landscape changes over time. It was realized that dramatic changes can occur over a very short time span. If you are still interested here are some resources which I recommend reading prior to a visit. Really helps to visualize what happened.
First of all read about Harlen Bretz: John Soennichsen, _Bretz's Flood_Then bring the two guide books by Bruce Bjornstad, _On the Trail of the Ice Age Floods_
