The Camp Fire Girls at the End of the Trail - Margaret Vandercook - Bog

The castle had been built before the first known palace in Europe. It was fashioned centuries ago inside the walls of a stone cliff with two taller cliffs rising on either side. Beyond was a break between, allowing a narrow entrance to the cliff dwelling from the outside. In front there was a small plateau of rock ending in a precipice, which descended with a drop of a hundred feet to a new ledge, and then came another still deeper fall.
