Tightly coiled to keep warm

We came across this young, male Wandering Garter Snake yesterday afternoon, when several of us went to 12 Mile Coulee. It's quite a tough walk, being steeply uphill and downhill for the most part. The weather was cold and overcast, apart from a short bit of sun, and it started snowing part way throughour walk. This snake was tightly coiled to keep warm and was tucked under a small bush. I had NO intention of getting any closer, to remove the slightly annoying dry blades of grass! I saw the tail end of a second snake slithering through the grass right next to this snake.
