NO. I ARCHITECTURE OF PUEBLO BONITO — JUDD I39 



level on the west side of the room passed under the east foundation 

 at a depth of 49 inches. An outside 5-foot-deep test showed that silt 

 surface continuing with a covering layer of sand upon which the 

 east-wall foundation was built. About 5 feet out from the wall a 

 pot-shaped storage cist 46 inches in maximum diameter and 50 inches 

 deep had been dug through that silt layer and into the sandy clay 

 beneath. 



In Chaco Canyon tireless winds carry sand upcanyon by day and 

 back again at night. From one direction or the other wind-blown 

 sand had piled up against the east side of 177 before our survey was 

 made and it is this sand, perhaps, rather than a down-valley slope 

 that accounts for the fact the surface there is 5 feet higher than 

 outside Room 118 at the opposite end of Profile A- A' (fig. 13). 



Our third cross section, C-C, begins at the Braced-up Qiff, 

 that colossus which for unmeasured years towered menacingly above 

 the walls of Pueblo Bonito, and passes thence through Room 189 and 

 diagonally across the East Court, above and below the last occupation 

 level, to Kiva B, Room 141, and our exploratory trench through the 

 West Mound. Like 225 and 177, Room 189 was a late addition to the 

 village; one of a single row of fourth-type structures built upon 

 abandoned foimdations of the Northeast Complex and abutting the 

 former exterior wall, of third-type masonry. Room 189 remains 

 unexcavated but, outside, sand and rock and water-borne silt have 

 piled up almost to ceiling level (fig. 15). 



Room 98, previously excavated, had a ceiling height of 8 feet 

 10 inches. Portions of its third story were still standing a few 

 years ago, the north door of 98B fitted with secondary jambs to sup- 

 port an outward-slanting doorslab (unpublished Hyde print No. 528). 

 Subfloor in Room 98 a foundation without identifying masonry is so 

 oriented as to connect it, indubitably, with a like foundation tmder 

 Room 295 and thus associate both with an earlier but rejected Late 

 Bonitian plan for an external row of third-type rooms (fig. 5). 



Kiva L, a third-type chamber 10 feet deep, was especially instruc- 

 tive because the south walls of third-type Rooms 290 and 291 arched 

 across its north bench on paired beams (pi. 57, left) and because its 

 cribbed ceiling was practically intact. Dismantling this latter, we 

 counted 195 selected pine timbers plus 135 shorter pieces in the 

 fourteenth or uppermost layer and perhaps 20 more lost through col- 

 lapse of the middle portion (pi. 56, upper) a total of over 300 trees 

 felled. On the floor, a 3-inch layer of blown sand and, above it, a 

 neighborhood dump that included 4,732 tabulated potsherds of which
