					Photo 21H 
					Photos 21H / 21J / 21K / 21L are zoomed in on individual 
					footprints; the prints aren’t very clear, as they were made 
					prior to a heavy rain, so try to meld them together in your 
					mind to picture what a fresh print would look like. The 
					prints measure 1¾ inch long by 1½ inch wide.  |
