Dugout Shelter Under 10ft (3m) of Snow - Solo Camping in Survival Shelter During Snow Storm

It snowed 30 inches (76 cm) in less than 12 hrs but I was comfy and warm in my dugout shelter (snow cave) under 10 feet (3 meters) of snow. I built a mass snow cave the size of a small cabin carved from the snow in the Alaskan Mountains. But while the solo camping was comfortable, the return home was very not, my poor car was buried and it took me 3 hrs to dig myself to freedom and only after a lot of help from strangers.
