That is the normal succession of things in this part of the world; you can see the various stages all over Scratch Flat. There is, for example, a small red maple swamp above my house on the northwest side of the drumlin. The swamp was probably a pond sixty years ago, but now in summer, unless you know your trees, you cannot distinguish it from the surrounding woodlands. It is only in spring, when the groundwater levels are high, that the remnant of the ice sheet makes itself apparent. Then the waters rise around the trunks of the red maple trees and, after reaching a critical level, run down across the small meadow to the north of my house.
