View is approximately W along the E/W axis (so-called “Riggs Line:” see elsewhere) across the basins ring, and close-up in foreground to suggest inferred N/S profile. Variously disturbed, reworked and redeposited tannish surface layers overlie the dark earth midden, itself incumbent upon the pale, yellowish Oolite. At the base of the midden near center, a hypothetical section through a downward penetrating “solution pit” suggests how they looked in vertical section. I believe more than 700 were recorded onsite, and occurred largely at random. (Attempts to demonstrate deliberate “configurations” and “runs” of these pits were largely unconvincing up to the time the site was closed). In the section projected here, if you look closely you can see a very tiny dimple or upraised “tit” at the bottom. This was found in many (but not all!) “solution pits,” and could usually in such cases be further linked to “tool” marks, scalloped edges, and “flaking back” around the openings – presumptive evidences of human manufacture (or modification perhaps, of pre-existent natural holes…). The “dimples” formed readily in test holes made on site by the dig directors with duplications of inferred ancient shell-tipped digging spuds.

The opening to right is the “sectioned” entry to the East Trench Extension (my designation).
