Entrance: Opening on southeast. Long, narrow entryway or vestibule 
indicated by two approximately parallel rows of 27 closely spaced posts, 
13 on one side and 14 on the other, ranging from 0.25 to 0.4 foot in diameter, 
with the rows spaced from 2.1 to 3.1 feet apart, and extending some 14.5 
feet southeast of the entrance. 
Floor: Tramped, slightly basin-shaped bottom of pit mantled with refuse. 
Fireplace: Single, off-center, oval basin (F15) measuring 1.8 feet in maxi- 
mum length by 1.3 feet in maximum width by 0.4 foot in maximum depth, 
filled with fine light-gray wood ash, burned sandy clay, fire-fractured cob- 
bles, and broken unburned animal bones and mussel-shell fragments. 
Subfloor cache pits: Four straight-sided cache pits in the center and north 
half of the floor area. F6, oval, measuring 2.65 x 2.25 x 1.7 feet (maximum 
length, maximum breadth, and maximum depth), filled with a mixture 
of dark sand and charcoal flecks, containing pottery sherds, unaltered 
flakes, and animal-bone fragments; F9, oval, measuring 2.9 x 2.4 x 1.5 feet, 
filed with a mixture of dark sand and charcoal flecks, yielding sherds, 
unmodified flakes, and broken animal bones; F11, oval, measuring 2.0 x 
1.45 x 1.7 feet, filled with soft, medium-dark sand containing four articu- 
lated bison vertebrae (F10), animal-bone fragments, etc.; and F14, cir- 
cular, measuring 2.95 feet in maximum diameter and 0.45 foot in depth 
(the upper part was scalped before the cache was recognized as such), 
filled with light-brown sandy clay which was lacking in artifact and refuse 
materials. KF6 and F9, indicated by dashed lines in figure 28, respectively 
underlay the firepit (F15) and the circular cache pit (F14), and hence 
were antecedent to the other two cache pits (F1l1 and F14). Noncon- 
temporaneous storage pits within or adjacent to dwelling structures, pre- 
sumably dug during consecutive or nonconsecutive seasons of inhabitation, 
have been observed repeatedly at occupation sites excavated in the Central 
and Northern Plains. 
Other features: A pair of bone hoes (F12), one complete, above, and one 
proximal fragment, below, and both made from left scapulae of mature 
bison, with the anterior and posterior borders sheared off and with an 
irregular perforation near the center of the body, in each case, on or near 
the floor in the southeast quadrant; two cobbles (undesignated), just north 
of F12 and approximately at the same level; and one group of osteological 
remains of bison (F138) including a horn core, long-bone fragments, a 
vertebra, foot bones, ete., on or near the floor just northeast of F12. 
Hovuse 2 (F25) in XU3; figure 29 and plate 28, b. 
Shape: Medium-size, circular; 26.4 feet in mean diameter. 
Depth of pit: Shallow, unfaced native earth; 0.7 foot to 1.05 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 pairs of central supporting posts (F2 and F3 designate one 
of two pairs, each; the other two pairs are undesignated) which varied 
from 0.35 to 0.75 foot in maximum diameter and were on radii of from 
2.6 to 5.0 feet from the center (calculated by drawing a cord from the cen- 
ter to the midpoints between the pairs of posts); and two rings of 
peripheral posts—a ring of 18 interior supporting posts ranging from 0.2 
to 0.8 foot in diameter and spaced from 2.3 to 4.2 feet apart (disregarding 
the 9.7-foot gap in the northeast quadrant where intervening postholes 
could not be found) on a mean radius of 10.7 feet from the center, with 
a divergence of from 0.2 to 0.65 foot; and a ring of 62 exterior supporting 
posts ranging from 0.25 to 0,8 foot in diameter and spaced from 0.8 foot to
