There is a series of deep gulches with steep sides, covered with brush. Where the surface has slid away indurated clay is exposed. The clay is hard and somewhat sandy, but sticky. The beds are about 2 inches thick and are divided by thin bands of rusty clay. The beds are horizontal and have the appearance of being water laid. The clay is laminated with fine lines so when it weathers it chips up in small pieces and looks like a pile of rotten pine bark. When worked up in the hand it bricks up and sticks together.
