That chunk of snow/ice with unknown objects melting in the front yard every spring. Seen in northern climates. Objects may include paper, plastic bags, car parts, and small animals unfortunate to be hit by a car that are then thrown to the side of the road via a snowplow.
Dude, the snow is really melting now. My whatsicle is starting to reveal some really wild stuff from over the winter. I'm pretty sure there's a cat in there.
