ent a fairly easy though winding and zigzag path to the entrance
from the top of the hill, and a rough and difficult way from the
bottom. It is a natural presumption that dwellers in the cavern had
well-constructed though necessarily devious pathways of easy grade to
both the top and the bottom of the hill; but owing to the loose nature
of the debris on the outside slopes all trace of these, when abandoned
or no longer kept in repair, would soon be obliterated by surface
wash, landslides, and the roots of trees.

By the side of the upper trail, at the bottom of the sandstone ledge
capping the hill, are many large blocks which have split off from this
stratum. On the flat surface of two of these are about 25 figures,
pecked into the stone apparently with a pointed flint implement. One
of them measuring 61/2 by 30 inches, shown in figure 11, bears some
resemblance to a flying bird. All the others are of uniform design, an
oval or elliptical figure with a straight line or bar passing through
an opening in one end. These vary from 4 to 18 inches in length; two
of them are shown in figure 12. Owing to the rough weathering of the
stones accurate tracings were not possible, but the illustrations give
a fairly correct idea of the inscriptions as they originally appeared.

The front part of the outer cave is partially filled with large rocks,
gravel, and clay, which have fallen or been washed in. A window-like
opening on the right, or south, side admits additional light. Near the
inner end the cave divides, one branch going to the southeast and
opening in the face of the bluff, the other turning north and
terminating abruptly near the doorway, which is worn through its rear
wall. A rough diagram (fig. 13) with some measurements is appended to
show this cavern's peculiar structure.
