The remants of this stone shack are one of the few reminders left that a large cattle ranch was once part of Gavilan Hills. The shack is only one room about 10' x 20' in size. On the same uninhabited property is an abandoned well, water tower, cattle loading dock, and some kind of ice or meat locker that is about the same size as this shack.
This house was inhabited by some questionable characters a few dozen years ago but I think they were just squatters. After the squatters left, the roof fell in and mother nature is working on taking it back over. The current neighborhood kids call this the "jail" and often play there.
