Shown in the background is the truck-mounted Giddings soil auger. Photo by Ed Murphy. Figure 6 shows the geologic cross section through the Jerusalem outlet. A distinctive feature in trenches JT1 and JT5 was a buried soil horizon that occurred at a depth of 6.5 feet below the ground surface. T' indicates trench location and numbers are drill hole locations.
Contours are feet above mean sea level.
North-south geologic cross section through the Jerusalem outlet. T' indicates trench location and numbers are drill hole locations. Contours are feet above mean sea level. At the bottom of both trenches there was a brown, moderately decomposed and compacted peat. The peat contained poorly preserved shells and clams and some seed pods were visible.
