Snow is definitely not my thing. Snow on the Grand Tetons is amazing looking however. My sister, Jonas and I had the whole park to ourselves on a -3 degree day (thanks to the sweet Celsius thermometer on the Hyundai). The knee deep snow kept us primarily stuck to the road for our photo ops.
We saw about as much wildlife as tamelife (humans). There was a wolf just observing the road for a few minutes and a moose that apparently Jonas talked to. Aside from that there was a ton of knee/waist deep snow all around the park. Thanks to the ice-fishermen who packed down a trail for us to get out on Jackson Lake a bit.
