2.3 feet apart, except at the entrance, on a mean radius of 10.6 feet from 
the center, with a divergence of from 0.1 to 1.0 foot. One S-shaped line 
of 10 extra posts varying from 0.3 to 0.6 foot in diameter, in the northwest 
quadrant, presumably represented a partition; one extra post measuring 
0.8 foot in diameter, just inside the entrance, in the southeast quadrant, 
and one extra post measuring 0.3 feet in diameter, just outside the outer 
ring in the northeast quadrant, may have been brace, replacement, or 
auxiliary roof-support posts. 
Entrance: Opening on the southeast. Long covered entryway or vestibule 
manifested by two nearly parallel rows of 21 unevenly spaced posts, 11 
on one side and 10 on the other, usually defined by fill softer than the 
surrounding matrix, and ranging from 0.25 to 0.55 foot in diameter, with 
the rows spaced from 4.5 to 4.9 feet apart, and running approximately 23.0 
feet southeast of the entrance and terminating in a small circular sweat 
lodge (F385), described hereinafter. Two extra posts inside the entryway 
and one extra post just beyond the terminus of the entryway, ranging 
from 0.3 to 0.35 foot in diameter, suggest interior and exterior partitions. 
Floor: Nearly level, untramped (?) bottom of pit mantled with sparse refuse. 
Fireplace: None found. 
Subfloor cache pits: Two straight-sided, circular pocket cache pits, re- 
spectively in the southeast and southwest quadrants of the floor area, just 
inside the outer ring of peripheral studs. Both F41, measuring 1.05 feet 
in diameter and 1.45 feet in depth, and F42, measuring 1.0 foot in diameter 
and 1.15 feet in depth, were filled with soft gray shaly sand but contained 
no artifact or refuse materials. 
Other features: One unworked complete though fragmented scapula of 
mature bison (F4), found lying horizontally on or near the floor in the 
southwest quadrant of the floor area; a cluster of four rock fragments 
(undesignated), found on or near the floor in the northeast quadrant, 
may have represented a slightly disturbed stone-platform hearth; one 
rock fragment, found adjacent to a posthole in the northeast quadrant, 
may have represented a post wedge; two other rock fragments—one in the 
northeast quadrant and one in the southwest quadrant—are of indeter- 
minate significance and may have been accidental inclusions. 
House 8 (F27) in XU2; figure 30 and plate 29, a. 
Shape: Medium-size, circular; 23.4 feet in mean diameter. 
Depth of pit: Shallow, unfaced native earth; 1.0 foot to 1.4 feet below ground 
surface. 
Framing (inferred from excavated postholes defined by the presence of wood 
or charcoal or, more often, by fill softer than the surrounding matrix) : 
Four central supporting posts (paired in northwest and southwest quad- 
rants), which varied from 0.45 to 0.75 foot in diameter and were on 
radii of from 5.2 to 7.0 feet from the center of the floor (calculated—in 
the case of each of the paired posts—by drawing a cord from the center 
to the midpoint between the pairs of posts) ; and two rings of peripheral 
posts—a ring of 11 interior supporting posts (one of which was bordered 
by three rock fragments, evidently post wedges) ranging from 0.3 to 0.7 
foot in diameter and spaced from 3.2 to 8.0 feet apart, on a mean radius 
of 8.2 feet from the center, with a divergence of from 0.2 foot to 1.3 feet; 
and a ring of 49 exterior supporting posts varying from 0.3 to 0.6 foot in 
diameter and spaced from 0.8 foot to 3.1 feet apart (except at the entrance 
and in the gap in the southwest quadrant where a small green ash was 
removed), on a mean radius of 11.7 feet from the center, with a divergence 
of from 0.1 to 0.9 foot. One northwest-southeast line of six extra posts,
