Down in the dunes…
…the sign of a snake.
The plates in my copy of the Peterson field guide to animal tracks suggest that the wide loops mean the snake in question was moving quickly. Apparently a more leisurely-crawling snake leaves a straighter trail. (Incidentally, the Peterson animal track guide is a delightfully idiosyncratic field guide, with as much anecdote- and sidetrack-filled narration as actual hard information on identifying tracks. I kind of love it.)
The snake stopped to investigate a ghost crab burrow, as well.
The next time a kid asks me if the the burrows in the sand are “snake holes,” perhaps I’ll think twice before saying no.
