Driving south on the Pacific Coast Highway, I was quite taken by the patterns in the earth resulting from erosion by the rain.  The soil is obviously soft and so has worn in patterns that are quite striking.  I think we were driving south when the light was best for the patterns.  The shadows were very pronounced.  On the way back I stopped to take some shots.  They were interesting but the light had moved to be more head on so the contrast was not as pronounced.  However, I still think the shapes made some interesting abstract patterns.
