The bench width in many Chaco Canyon, Mesa Verde, and Great Sage Plain “kivas” as well as Paquimé granaries indicates a variety of uses which are consistent with dehydration towers and structures.
Hohokam Granary? (below)
Mesa Verde Multiple Granary Benches 3-6” wide
The Hohokam had a less well understood structure that had a raised floor, fire pit, and schist stone risers; it is possible that this functioned in the same way as Chaco kiva/silos and Paquimé olla/granaries (Haury 1932).
Kin Ya Chaco Outlier Multiple Granary Benches 3-4” wide
Everything at Chaco especially Pueblo Bonito was done on a grand scale. Even the granary benches average 4-6” wider than other granary benches.
The Lowry “painted kiva” is the “smoking gun” for a grain or meat smoke house. There were 25 levels of plaster excavated, and many of the layers had soot between them. The plaster and the floor should have been tested for corn pollen and residue. The drying racks are built into the pillars and are evident in some Mesa Verde sites as well (Lowry smoker granary) (above three photos).
The bench width of 3-6 inches in the Sky Island Paquimé site granaries is consistent with the bench width in many Mesa Verde “kivas” or round rooms (left two columns).
