relation to one another, it seems probable that these structures were 
used as temporary storage places for harvested corn awaiting trans- 
portation to the winter habitations. Of the larger structures six 
were found and excavated. . 
Ruin 1 
This is a small cliff-house built in a recess about 20 feet up the side 
of a detached rock hummock in the canyon bottom (fig. 1 and pl. 3). 
The exposure is southeast. The cave floor slopes rather steeply from 
. front to back, and the rooms are clustered in the eastern end of the 
cave, leaving a considerable clear space at the west. The house con- 
sisted originally of six or eight rooms (fig. 2), but is in an advanced 
stage of ruin, the walls being much fallen and no roof timbers left 
in place. This condition is rather difficult to account for, as the over-

hanging roof of the cave completely shelters the buildings from rain 
and, outside of one quarter, there is no sign that the place was rav- 
aged by fire. The masonry is composed of irregular slabs of sand- 
stone, roughly coursed, set in adobe mortar and abundantly spalled. 
The best work is seen in the front wall of room 6, which is built 
along the shelving edge of the cliff and stands very true and even, 
8 feet high (pl. 4). The precarious position of this wall, its insecure 
footing, and the fact that it formed the support for several struc- 
tures behind it, necessitated careful and solid construction. That this 
was provided shows that the more careless work on the other rooms 
was not due to inability to produce better. No data as to size or 
architecture of doorways or method of roofing could be gathered. 
Rooms 1 and 2 have almost completely fallen away, only two 
courses of the south wall appearing. Their former shape is clearly 
indicated, however, by adobe mortar still adhering to the rock along
