Figure 1. Topographic map showing two small, ice-marginal deltas, which were fed by an ice-tunnel stream as evidenced by the esker "tail" on the north side of the deltas. At the time they were deposited, the south edge of the glacier was just where the esker and delta come together. Based on a radiocarbon date on organic material in sediment in a core taken from a nearby pond, this was approximately 12,800 radiocarbon years ago (about 15,000 calendar years). Figure 2 and Figure 3 are from excavations cut into the delta closest to Lindsay Lake.
