I took a hike today with my wife at Bodega Dunes. We hiked about six miles in a little more than two hours.
Low clouds and fog played tag with us, sometimes blowing in from the sea to make our early afternoon outing cold and dark.
At other times the fog retreated back over the ocean revealing a blue sky. In those moments, the sun shone warmly on us.
As I walked on the wide expanse of sand I wondered whether most of it flowed out of the Russian River estuary, a few miles north of where I stood as I took this photo. Most of it, I suppose.
I wondered, too, how many eons it would take an estuary to build dunes like these.
