SBA-1807 sits on the high coastal bluff west of Canada de Alegria (Figures 5-1 and 2-2). The site was recorded in 1977 by Kuffner and Wallof (Clewlow 1978), who described a small (10 × 30 m) shell midden located on a slight knoll between the sea cliff and the railroad tracks. Between 1977 and 1983, this area appears to have been destroyed by grading for railroad maintenance. In 1983, archaeologists with WESTEC Services recorded a second midden area at SBA-1807, this one located north of the railroad tracks. Two test pits were excavated at this time (WESTEC 1984a:21), although the site was not dated. A shell sample from one of WESTEC’s test pits was radiocarbon dated to about 8400 calendar years ßP (cal BP), and the contents of the test pits were analyzed in more detail during a shovel-testing program designed to define the site boundaries within a proposed pipeline alignment (Erlandson et al. 1984; Erlandson 1985). More surface collection and excavation was done in 1985, when archaeologists from UCSB excavated in peripheral midden deposits south of Rancho Real (Units 1–8) and in a discrete cluster of chipped and ground stone artifacts to the southeast (Units 9–11, and 13–18). Limited excavation (Unit 12) and surface collections also were conducted in the central midden area north of Rancho Real. Our investigations at SBA-1807 were completed in the summer of 1986, when 31 test units were excavated in the southeast (SE) locus, 9 units in the southern midden periphery, and 2 units (19–20) in the central midden area. In all, just over 42 m3 of sediment were excavated during UCSB’s 1985-86 investigations: 3.7 m3 in the central midden area, 11.2 m3 in the southern midden periphery, and 27.4 m3 in the SE locus. Later, many chipped and ground stone tools were collected from the SE locus during controlled backhoe trenching (Trenches 1–4) and monitoring of construction grading of a large “fault trench” in the same area.
