This creek drains the Little Park*, and it’s already delivered most of the rainfall from earlier this week downstream. The streambed is dissected, or deep below the adjacent ground surface. This is the result of sediment deposition in the valley, as well as downcutting by the drainage after the forests were removed in the catchment area. So, the pattern you see here is very historic, and relatively recent. The piedmont sure looks a lot different now than it did 500 years ago.
