Provincetown at low tide

I lived in Provincetown, Cape Cod, Massachusetts from 1970 through 1989. I spent many hours on the Harbor at low tide photographing the patterns the receding tides made on the sand. Some of these patterns reminded me of other worldly configurations. My favorite place to photograph was towards the tip of the Cape at "New Beach," where the tide was especially low and the sand patterns went on into the horizon. This photo shows one of many patterns. My bare foot is seen in the bottom right-hand corner of the photo.
