Yesterday afternoon I posted photos of taken in our backyard leading to the Celery Farm.
The three prevalent theories were snowshoes (which no one used in my yard that I know of), deer (just too big and inconsistent with all other deer tracks in the Celery Farm) and "more than one foot/paw/etc. in each place" (which is what I wondered as well).
The thinking is that it is the entire animal (think "rabbit," perhaps), jumping from spot to spot in the deep snow.
Because of the comments on the blog and the blog's Facebook page, I measured the tracks.
They are roughly 8 inches long and 5 inches wide, and the distance between the tracks went from 4 feet to 3.5 feet to 3 feet...
The mystery creature conveniently dropped a penny by the track so you can get a sense of scale.
