Earl H. Morris conducted an excavation of this open talus site in Animas Valley in 1938-1939. It was the first site where dwellings had been found of the early Basketmakers with actual house structures, one of which he describes as follows:
A site for the dwelling was secured by digging a drift into the steep hillside and piling the excavated earth and stone out in front until a terrace large enough to accommodate the projected house had been provided. The floor area was scooped out to shallow saucer shape—in this case 9 m. in diameter—and coated with mud. At the margins, the mud curved upward to end against the half-buried foot logs which were the basal course of the wall. The walls were composed of horizontal wood and mud masonry. They rose with an inward slant to a little better than head height, then were cribbed for a distance to reduce the diameter of the flat portion of the roof, which was of clay supported by parallel poles, The arc of stones was a retaining device placed to hold back the ever-growing accumulation of refuse that was dumped at the brink of the terrace.
