The Sweet Stillness of the Woods

By Boak Wiesner

The explosive “pe-keek” of a Hairy Woodpecker greets me as I go into the woods around the little marsh that’s perched up high on the west side. A meandering circumperegrination of it has become one of my favorite “beats” at the Arb. Beethoven himself, even troubled by deafness, would walk for hours in woods, experiencing the trees, the flowers, the rocks – none of which needed hearing to be enjoyed. The grey fog and light snow enhance my experience immeasurably.

Where once open water stood, years and years of accumulating plant material has supplanted the water; lo!, a marsh has succeeded the pond.

This is the only place at the Arboretum I have yet found where they are so abundant and it gets me to wondering about that “dark laboratory called the soil” and what “bottlenecks” have been cracked open right here so that there are so many in one place.

DSC_0161Another glaring clue to how this landscape was made, that is, as till deposited by glaciers, is a nice chunk of dark basalt. Since the bedrock ‘round here is light-colored Platteville limestone, this rock is a stranger. With a little examination of its crystal size and overall color, one could probably figure out just where it came from north of here. Since its shape is still pretty angular, one can tell it wasn’t transported by water, and, besides, how would it have ended up here on the hill?
