Mound B
This low, approximately circular mound was located on the floodplain of Cypress Creek, about 125 feet south of the stream channel, at the south end of the lake ([Fig. 1]). A shallow depression about eight feet across lay just southwest of the mound, and a similar but smaller depression was recorded at the northeast edge of the mound. These features probably are borrow sources. An intrusive pothole, located near the center of the mound, was three to four feet in diameter at the surface, but fortunately it proved to be quite shallow and damage to the mound was slight. The maximum diameter of Mound B, measured north-south, was 55 feet ([Fig. 4]), and the mound reached a maximum height of 2.8 feet above the floodplain.
Mound B was staked for excavation with the usual grid of 5-foot squares oriented on magnetic north. The base stake was 100 feet south and 100 feet east of the approximate center of the mound. Excavation was carried out by the quadrant method as previously described, the southeast and northwest quadrants being excavated first, the southwest and northeast quadrants last. Each quadrant was taken down by ½-foot levels which were keyed to the vertical reference datum. In addition to work in the mound itself, the area immediately south of the mound was tested by means of trenches ([Fig. 4]). The trenches were dug in ½-foot levels measured from the surface of the floodplain at each square.
The excavating and recording methods used at Mound B were generally the same as described for Mound A.
