Solution Holes

No, this isn't a photo of a street in my hometown of Pittsburgh. Rather, they're solution holes, or what we like to call nature's potholes. The rock underlying much of South Florida is limestone, basically calcium carbonate. In areas where the rock is exposed or near the surface, rain water collects as does fallen leaves. The decaying vegetation acidifies the water, which, over time, dissolves the limestone and creates these holes. This same process on a much larger scale creates dome and strand swamps that are present throughout South Florida. By the way, you'll find these holes inside our next stop.
