Strange dirt effect

We encountered this strange bit of dirt on the way to the agate beds on Red Top Mountain. It looked strange and we suspected some sort of rodent activity. Later we spotted the ground squirrels and had our answer. The flowers are from onion bulbs--we suspect the squirrels were dining on them. The tunnels were in great abundance; the snow melt underway with some patches still evident. I guess if you hibernate you wake quite hungry.
