We stayed the night out on the Flint Hills near an old farmstead. The home had been completely removed except for part of the foundation. The bottom part of the barn was mostly complete and in exceptionally good condition.
The cave, however, was almost completely intact. The stones were cut and laid by someone with masonry skills. The curves up to the top are perfect with the keystones right down the middle. We wondered how many times the family took refuge from prairie storms in this solid shelter along side the food stock.
