Yellowstone

We are in Yellowstone today but we will only be able to stay for one day because they are expecting snow on Sunday and we don't want to get caught in a storm. Because the days are so short (10 hours of light/8 hours of sunshine) we won't be able to hike in anywhere tonight so we will stay at the campground at Mammoth. It has been very cold, the ranger at the Old Faithful visitor's center said it was 20° last night here. At our campsite on Phelps lake in Grand Teton our water had a sheet of ice on top in the morning but when we got back to the truck the other gallons of water were frozen solid. Because it has been so cold and there is snow on its way we will drive all the way to Erik's family's house in northern Idaho tomorrow to clean off and warm up.
