ed here. Section 3: HydrologyPart I: Bedrock KnobThe Bedrock Knob is particularly susceptible to weathering by rainfall because there is little vegetation to intercept the water. Material is washed down from the Knob and becomes part of the sandy soil surrounding it. The valley on the northern side of the Knob concentrates runoff in a shallow swamp that is evidence of poor drainage. Drainage problems were increased when the road was built because it blocked drainage from an area that was previously well drained. It is evident that the area was well drained at some point, because the stumps of trees stand in the middle of the swamp. Table 1 in the Appendix contains the results of hydrologic test on the swamp water. Part II: Bridgenorth Esker, Burnham Park, and the Rice Lake Drumlin.The hydrology of the Bridgenorth Esker was inferred through observation since there were no nearby water bodies to be tested. At the time this site was visited, it was raining and this allowed for observations on the drainage of the area. Water pooled on the surface where human activity was present because the ground had been compacted by man and machine. The esker itself drained very well and no pooling or surface runoff was noted. It is common for eskers and areas of glacial deposits to drain well because the permeability of deposits is high. The Mark S. Burnham Park was not subject to hydrologic tests, however, certain factors of water movement can be observed. The park contains an original old-growth forest that suggests a high degree of interception occurs before water can enter the soil. An extensive canopy, fallen trees, undergrowth, and a thick leaf litter all prevent runoff and direct percolation into the soil. Even when water reaches the soil it can percolate quickly through the sand and gravel of the drumlin. Most of the water probably drains to the swamp and Meade Creek in the southern corner of the park. The swamp exists either...
