KIDDER—GUERNSEY ] ARCHEOLOGICAL EXPLORATIONS IN ARIZONA 83 
ancient people used for an entryway a vertical fissure at the north 
end, up which there was pecked a series of shallow foot and hand 
holds. From the top of the fissure to the first of the rooms, foot- 
holes had been cut along an unpleasantly tilted and crumbly ledge 
18 inches wide, with a 30-foot drop and a 70-foot slide below. Be- 
fore guying up our poles directly into the rooms, we had climbed to 
the top of the fissure and attempted the ledge. We found, however, 
that the ancient steps were too much worn down and shallowed by 
sand erosion for us to use. It was evident that no one had entered 
this cliff-house since its abandonment as a dwelling place, although 
two or three little granary rooms on the lower benches had been 
used by the Navaho as caches. 
Fie. 10.—Ruin 3. 
Once in the ruin, we found it to consist of a single line of 10 living 
rooms with a continuous front wall, built flush with the edge of the 
cliff. The back part of the cave slants up too steeply to have been 
available for buildings (fig. 11). There is no kiva, nor could we find 
any trace of one in the valley below. The rooms are of two quite 
distinct types: at the southern end come four chambers built of the 
usual adobe-laid masonry of the region, each having one or more 
doorways and each having once undoubtedly been roofed; beyond 
these the rooms are somewhat larger and have walls varying from 
18 to 28 inches thick, made of large irregular slabs of sandstone piled 
up without mortar and depending for stability entirely on their 
weight. At present the walls at the south end of the line average
