During the winter months, the only plowed road in Yellowstone is the one that goes across the north side from Mammoth and out to Cooke City. So the only thermal features we saw were at Mammoth. We spent part of an afternoon walking around the travertine terraces. It’s an ever-changing spot with hot springs drying up in one place showing up new places all the time. I particularly enjoyed the contrast of the hot water, the snow, the steam and the frost.
Rabbit?
