The residential areas at Slack Farm included structures (house basins), small and large pits, and hearths. Investigators documented portions of at least 40 houses. Most were shallow basins bordered by wall-trenches. Structure walls had been made of wattle and daub: a woven lattice of wooden strips plastered over with clay baked hard by the sun. Each house had a prepared interior clay hearth. When residents abandonned their homes, they intentionally broke old cooking and serving vessels and left them behind in the hearth.
Large pits were located near structures. Many had diameters greater than six feet and were more than six feet deep. Residents used these “underground silos” to store dried plant foods. Sprouted corn kernels recovered from some large pits suggested that a portion of the stored corn may have spoiled.
If corn accounted for 65 percent of the diet (and assuming residents ate between 2,300 to 3,500 calories a day per person), then the contents of these storage pits could have fed from 7 to 12 individuals for a year. When the contribution of meat, fish, and wild plants to the Caborn-Welborn diet is added to the equation. the food stored in these silos may have fed even more people.
The most distinctive decorations on Caborn-Welborn Decorated jars are trailed, incised, and/or punctated designs on jar shoulders. These designs consist primarily of incised or trailed lines that form opposing triangles. Archaeologists have interpreted these designs as part of a sun symbol, with the center of the sun corresponding to the jar mouth and the designs, the sun's rays.
