I’m fascinated by the geomorphic traces left by the rise and fall of Lake Mead – human scale (egret scale?) shoreline terraces. This is on the northern bank above Boulder Harbor. The bird, shown for scale (I don’t have a rock hammer, it’s a great egret, so quite large), hangs out there because of the fisher people.
