The midden stain at Site 15Hr22 measured 360 by 459 feet. The plaza measured 190 by 262 feet.
Native residents arranged their village in concentric activity zones around the central plaza: cemetery or mortuary zone, residential zone, and trash disposal zone. Investigators estimated that 25-30 structures stood in the residential zone, housing between 150-180 people. No palisade around the village perimeter was documented.
A low, conical earthen burial mound was located along the northwestern plaza edge. It measured 55 by 75 feet. Undoubtedly much taller originally, it stood 1.5 feet tall when recorded in 1992.
Although some adults were buried in the mound, most adults and adolescents were interred indvidually in shallow pits next to the plaza. The dead were laid to rest on their backs in an extended position. In some cases, several limestone slabs were placed over a grave. The presence of a lens of ash and burned wood directly above the slabs, and the presence of hearths adjacent to the graves, suggest that feasting and mortuary rituals took place during burial.
Investigators documented three houses at Site 15Hr22. Structure 1 was the only one they excavated completely. It measured approximately 13 by 16 feet, with the long side facing the plaza. The house was in a basin, and individually-set posts lined the basin edges. The house had a prepared floor but lacked a prepared central hearth. Pits - large shallow basins used for trash disposal - were found behind the houses.
