Photograph of an otter's dust-bath site in Back Bay Wildlife Refuge. The dirt-and-gravel surface is disturbed into a vague pattern of curves and peaks, marking where the otter rolled. I was disappointed that there weren't any clear footprints, only wriggle-prints.
When a group of hikers approached from the other direction, the otter dashed into the water too quickly for my photography reflexes.
All that was left were wriggle-marks. If I hadn't seen the dust bath, I couldn't have read "otter" in this pattern.
