2004. A small test pit adjacent to the midden site was excavated and revealed that the upper 1 m of the midden was comprised of oyster shell and pottery fragments. Near the base of the pit was a clay-rich deposit with some quartz. The site was visited a second time on January 5, 2005. Another test pit near the midden site was excavated. It revealed a similar internal structure. The material graded from oyster shell in the upper meter of the pit into clean quartz sand at the base of the pit. A sample site was selected on the shoreline to avoid having to core through the oyster shell layer of the upper midden. A vibracore was collected and 3.5 m of sediment was recovered. The site location is shown in Figure 4.1. Table 4.1 lists the samples collected at the site. Figure 4.3 shows the sample location. SVI002 Site SVI002 was located within ridge set E, at the intersection of Road 5 and Road G. The site was visited on July 24, 2004. A 3 m deep trench was excavated perpendicular to the dune crest. Three push cores were collected from the trench face, for OSL dating. At each of the push core locations a small grab sample was collected for granulometric analysis. A vibracore was taken from the center of the trench floor. Only 0.6 m of sediment was recovered because the vibracore hit resistance during penetration. The site location is shown in Figure 4.1. Table 4.1 lists the samples collected at the site. Figure 4.4 shows the sample location. SVI003 Site SVI003 is located within ridge set E, at the intersection of Road 5 and Insulator Road. This site was visited on July 23, 2004. A trench was excavated. The trench faces showed evidence of iron staining and bioturbation. Care was taken to avoid these areas during sample collection. Three push cores were collected for OSL dating and three grab samples from the same locations were collected for granulometric analysis. The site location is shown in Figure 4.1. Table 4.1 lists the samples collected at the site. The sample locations are shown in Figure 4.5. SVI004 This site is located 50 m north of Road E, on Road 5. This site is located within ridge set F. The site was visited on July 23, 2004. A small area on the crest of the ridge was cleared and a vibracore was collected. 1.9 m of sediment was recovered. The site location is shown in Figure 4.1. Table 4.1 lists the samples collected at the site. Figure 4.6 shows the location of the vibracore collection. 57
SVI005 This site is located just west of Pickalene Bar, on the south side of Pickalene Road. The site is within ridge set C. The site was visited on January 4, 2005. A 0.4 m deep test pit was excavated. The pit showed gray sand with a small amount of clay. The base of the trench contacted the water table. A vibracore was then collected using a 20-foot section of aluminum irrigation pipe. 3.4 m of sediment was recovered. The site location is shown in Figure 4.1. Table 4.1 lists the samples collected at the site. SVI006 This site is a midden site located just off of Pickalene Road within ridge C. SVI006 was visited on January 4, 2005. A sample trench was excavated by hand adjacent to the midden. The trench showed clay-rich sediment, grading into sandy clay. A push core was collected for OSL dating from the lower sandy clay layer. The site location is shown in Figure 4.1. Table 4.1 lists the samples collected at the site. SVI007 This site is located at the northern end of Road 5 and represents the oldest ridge within ridge set D. The site was visited on January 4, 2005. A vibracore was collected from the middle of the road after verifying that there were few signs of disturbance. Approximately 4.7 m of sediment was recovered. The site location is shown in Figure 4.1. Table 4.1 lists the samples collected at the site. SVI008 This site is located on the northern shore of Big Bayou. It is only accessible by boat. The site was visited on January 5, 2005 and a vibracore was collected. Approximately 1.9 m of sediment was recovered. The site location is shown in Figure 4.1. Table 4.1 lists the samples collected at the site. SVI009 This site is located on the west side of Road 4, just north of the intersection of Road 4 and Road D. The site was visited on May 5, 2005 and a trench was excavated perpendicular to the ridge crest. This ridge is one of the largest in ridge set G. The site location is shown in Figure 4.1. Two push cores for OSL dating and eight grab samples for granulometric analysis were collected. Four of the grab samples were collected along a bedding plane. The remainder of the samples were collected along a transect stretching from the top of the trench to the base of the 58
