I live in the suburbs of Washington DC where it recently snowed. I was admiring all of the tracks left behind by wildlife of all kinds when I came across these prints, that I was unable to recognize from charts of common animals prints online.
What is unique about them, is that each print, has 3 points, and there is only one straight line of prints, about 2-3 feet apart, where as I would imagine a deer, or other 4 legged animal would leave staggered footprints. We have a lot of deer in these parts but these dont seem to match deer print patterns I've seen online.
Each print is about 5 inches by 4 inches at their widest/longest points (they are longer then they are wider).
Note, the snow has melted somewhat since they were initially made.
