the center, with a divergence of from 0.1 foot to 1.0 foot. Two posts on 
the east side—one between the inner and outer peripheral rings, the 
other beyond the outer ring at the entrance—each of which measured 
0.3. foot in diameter, and an irregular line of three posts, measuring from 
0.8 to 0.4 foot in diameter and roughly paralleling the south line of the 
entryway supporting posts, just outside the outer ring of posts, may 
have represented brace, auxiliary roof-Support, or partition posts. 
Entrance: Opening on the east. Long entryway or vestibule indicated by 
two nearly parallel, albeit undulating rows of 21 rather evenly spaced 
posts, 11 on one side and 10 on the other, ranging from 0.2 to 0.35 foot 
in diameter, with the rows spaced from 2.5 to 3.0 feet apart and running 
about 11.8 feet east-southeast of the entrance. 
Floor: Nearly flat, untramped (?) bottom of pit mantled with some refuse. 
Fireplace: One central, subcircular basin (F19) measuring 2.8 feet in maxi- 
mum diameter and 0.4 foot in maximum depth, filled with a mixture of 
burned shaly sand and light-gray ash containing an incised cuboid pipe 
of limestone and a mussel shell; another subcircular basin (F383) meas- 
uring 1.75 feet in maximum diameter and 0.3 foot in depth, filled with a 
mixture of fire-reddened sand and gray ash, directly east of the central 
fireplace; and a third subcircular fireplace (F18) measuring 1.0 foot in 
maximum diameter and 0.25 foot in depth, filled with light-gray ash under- 
lain by burned shaly sand, in the southeast quadrant. This feature con- 
tained the hole of one of the inner ring of peripheral supporting posts. 
Hence, it may be inferred that this was an open hearth which antedated 
the construction of the dwelling. 
Subfloor cache pits: Two pocket cache pits, one in the southwest quadrant 
(F39), measuring 0.9 foot in maximum diameter and 1.05 feet in depth, 
and one in the southeast quadrant (140), measuring 0.65 foot in maximum 
diameter and 2.0 feet in depth. Both contained soft gray shaly sand but 
no artifacts or refuse materials. 
Other features: One granite boulder-anvil (F388), battered on the upper 
surface and measuring 1.25 feet by 1.1 feet by 1.3 feet, was found lying on 
the floor directly west of the central fireplace and just inside the inner 
ring of supporting posts. 
BOWER 
In XU16, at depths ranging from 0.5 foot to 1.1 feet below the surface, were 
found 11 postholes, ranging from 0.35 to 0.45 foot in diameter; a subcircular 
fireplace (37), measuring 2.1 feet in maximum diameter and 0.4 foot in depth, 
which contained shaly sand, gray ash, and three large animal-bone fragments; 
and a cluster of three rock fragments and three individual rock fragments 
(fig. 82). While the postholes formed no clearly discernible geometric pattern, 
their distribution around the fireplace suggests that they represented the sup- 
porting posts for the cross-stringers and rafters of an open-sided bower (F48), 
which may have had a smokehole directly above the fireplace. The rock frag- 
ments were possibly accidental inclusions in the matrix. 
SWEAT LODGE 
Just beyond the terminus of the entryway of House 2, in XU3, were found, 
at a depth of from 0.6 to 0.8 foot below the surface, eight postholes which formed 
an almost perfect circle around a cluster of fragmented cobbles (fig. 29). The 
posts, varying from 0.2 to 0.35 foot in diameter and spaced from 1.55 to 3.1 
feet apart, were on a mean radius of 2.65 feet from the center, with a divergence
