Figure 2. Pit stratigraphies for excavations 91-001, 91-002, 91-020, 91-031, and 91-038 pertain to site UF, whereas excavations 91-053, 91-054, and 91-055 pertain to site LF in figure 1. Given are the location of the excavations; the approximate depth of the excavations (depth scale is in 2.5-centimeter increments); the lithostratigraphy of the excavations; and sample location and number. In all but two excavations, three units could be distinguished: from the top-down, a loose yellow-reddish layer, capping a light-gray, massive, structureless, moderately consolidated layer, and a massive, structureless, consolidated dark-gray layer. Also given are the locations of sediment and microfossil samples (ASF 91-).
