16 PROCEEDIlSrGS OF THE NATIONAL MUSEUM vol. 77 



Room H^ apparently a ceremonial chamber, stands between court 

 13 and room 15. Its floor is entirely of native rock, partially worked 

 down in the west corner. On the northwest side a ledge slopes from 

 the upper west corner to the floor at the north. The west half of 

 this ledge was built up with masonry, filled with debris and capped 

 with slabs 31 inches (0.78 m.) above the floor to form a shelf 12 

 inches (0.31 m.) wide at the northwest and 24 inches (0.61 m.) wide 

 at the northeast. 



The roof is supported by two central northeast-southwest beams; 

 three others, side by side, lie next the cliff. On these beams fifteen 

 cross poles support a layer of willows, mud covered. Ceiling and 

 walls are heavily smoked. The lower two-thirds of the southeast and 

 northeast walls are plastered while the southwest and northwest sides 

 remain unsurfaced. Several small ovals and circles, made by press- 

 ing a pointed instrument into the new plaster, appear on the south- 

 east wall; also, several casually incised lines. Two pegs protrude 

 from the upper northeast side. Apparently after completion of 

 the room, a vent about 4 inches in diameter was cut through the 

 southeast wall, 14 inches (0.35 m.) below the cross poles and 4 feet 

 6 inches (1.37 m.) from the east corner. 



A door opens through the middle southwest wall with its slab 

 sill, slightly grooved where a stone ax was sharpened, at the court 13 

 level. Just within this door and continuing from its. sill a sand- 

 stone slab which has settled 2 inches at the north tops a masonry 

 platform 16 inches (0.41 m.) wide and 16 inches high. This plat- 

 form lies between the wall and a masonry fire screen, 25 inches 

 (0.64 m.) high by 27 inches (0.69 m.) wide by 10 inches (0.25 m.) 

 thick, capped by a single stone. Pecked into the rock floor at the 

 northeast base of this screen is an ovoid fireplace, 25 by 18 by 41^ 

 inches deep (0.64 by 0.46 by 0.114 m.). In the ceiling above the 

 platform an unrimmed smoke vent measures 6 by 10 inches (0.15 

 by 0.25 m.). Northwest of fireplace and platform the cave floor 

 slopes upward toward the cliff; in this sloping surface four steps 

 were pecked. 



Four feet six inches from the north corner and 8 inches (0.20 m.) 

 above the floor a second door opens into room 15. Loops for door 

 fasteners protrude at points 8 inches and 12 inches (0.31 m.)^ 

 respectively, from its grooved jambs. 



Five pairs of pecked eyelets and others, unfinished, appear on the 

 northwest cliff above the roof; here also is a narrow groove where 

 some implement was pointed. 



We repaired the walls, recapped them with a single course of 

 stones, and patched several holes in the roof.
