Last day, late in the season, usually not the time of year for scrape activity, wide open area (not your usual scape location), snow on the ground covering browse, no overhanging lick branch (I've never seen a scrape that wasn't under a branch where scent from eye glands could be deposited). I'm thinking this could have been a doe or any deer for that matter that was pawing the ground in search of feed. I think you might be better off looking elsewhere.
