the cave floor directly in front of the opening, though some distance 
out from the cliff (pl. 30, 6). The cave was apparently formed by 
the falling out of large pieces of rock which broke off from the 
cliff along the line of cleavage. Débris from above has filled the 
lower part of the break and formed a base for the floor. 
The entrance is a triangular opening 50 feet wide at the base and 
20 feet high at the apex. Reference to the plan (fig. 82) will show

a bend in the eastern wall; and a reentrant angle in the west wall 
opposite the bend partly divides the cave near the center, thus form- 
ing a front and a rear room. The extreme depth, measured from 
a point directly under the entrance, to the back of the rear room is 
50 feet; the line of shelter extends some 20 feet beyond this. The 
opening faces the south. Irregular arches form the roof, which 
slopes gradually to where it meets the floor at the rear.
