KIDDER-GUERNSEY] ARCHEOLOGICAL EXPLORATIONS IN ARIZONA 91 
no inducement for excavation. The pictographs consisted mainly of 
hand prints in white. The “owl” is shown in plate 95, b. On the 
top of the Black Mesa the broad-leaf yucca was seen for the first time 
in this region. 
SurFAcCE Rurns at THE Heap or Kayenta VALLEY 
The work of excavating the caves in Kinboko and the other inves- 
tigations in that district having been completed, camp was moved to 
below the mouth of Marsh Pass, where the rest of the field season 
was spent in exploring a part of the uptilted and broken “comb” 
lying between Skeleton Mesa and Kayenta Vailey (see pl. 1). Owing 
to the rugged character of the country, this could be accomplished 
only on foot, which limited the area examined to a radius of not 
more than 5 miles (pl. 32, a, b). 
Opposite the new camp, which was pitched on the east bank of 
Laguna Creek at the entrance to the pass, were remains of quite an 
extensive surface ruin. These lay along the perpendicular escarp- 
ment of a detached portion of the comb. No walls were visible on 
the surface, but a number of low mounds covered with building 
stones probably conceal the foundations of rooms. At this place 
there is also a granary made by walling up the front of a small re- 
cess under a large, irregular rock standing alone some distance out 
from the cliff. Its doorway is a rectangular opening 17 by 19 
inches. The most interesting feature of this neighborhood is the 
great number of pictographs worked in the smooth face of the cliff; 
sketches of a few of the most striking ones are given in plates 89, h, 
a; 91, ¢, e, i, g- 
Caves IIT ann IV 
Climbing up and through a narrow break between the section 
of the comb back of the surface ruin,and the next segment, two small 
caves were found (see pl. 1). The first, which can be seen from 
the bank of the creek, contained no cliff-house structures. The 
low roof was much blackened by smoke. As the floor was saturated 
with moisture from a seeping spring at the back, no digging was 
attempted. The second cave is near the top of the comb and was 
reached by passing through a narrow fissure and up a rough talus 
composed of huge blocks of stone. The cave itself is a crevice in the 
rock, 35 feet deep, 30 feet wide, and 20 feet high at the front. Its 
back is completely closed in by a well-built wall, forming a room 
11 feet deep and 8 feet wide at the front; access to this chamber is 
gained through a doorway 17 inches wide and 19 inches high (pl. 
33, 4). Two long, narrow slabs of stone serve as lintel and as sill. 
Two small sticks cross the top of the doorway just under the lintel;
