I just noticed this today! something has burrowed around my raised bed and I'm very worried. this is my first year gardening and these are my main vegetables, I would hate if some critter ate them all

I have beets and two kinds of carrots in here, and I'm afraid something might be getting at them from the looks of this trail? I honestly don't know what it could be, but if you have a guess and some ideas of what to do about it please share, I have no idea what to do!
