Kevin and I made some progress toward my goal of spending the night in a snow cave. (our dog Ellie helped a bit too!) We created a snow cave in our yard after a huge spring snow storm (almost 3 feet of snow). Since it was our first attempt at a snow cave, we decided to see how it lasted overnight. In the morning, the cave was in tact, but as it warmed through the day, the cave began melting quickly. Now that we have the general idea, next winter we'll give it another try and hopefully spend the night!
