She and Joey buried him in the adjoining sheep pen. The remains of a sheep pen and a well can still be seen. I kept walking around [the perimeter of my] sheep pen, and noticed large metal wire-cutters. The sediments preserving these tracks later became the Sheep Pen Sandstone. At the time of the inspection, 1992, the building was used as a sheep pen. In British English, a sheep pen is also called a "folding", "sheepfold" or "sheepcote".
