Cows as Sculptors?

These aren't my photos, they were forwarded to me by friend Terry, who is keeping a low profile. Not only that, but the title to the post is also by him. I just couldn't pass up posting this (taken when there was a break in the rain here). Thanks, Terry! 

Edit: Terry says this is in Round Valley, a wonderful Park with shy cows in it that exists East of Mount Diablo.
