No Tent Winter Camping During Snow Storm - Exploring Natural Stone Maze

Me and my 5yr old son hiked to an amazing natural stone maze hidden in the Blueridge Mountains. We went winter camping without a tent but the temperature dropped 20 degrees and it snowed on us. But luckily we didn't let that stop us and while hiking we found a natural stone maze and built a primitive survival shelter in between some large rock outcroppings and while it was well bellow freezing we were very cozy.
