The Shack Landscape and Its Restoration: A Natural history
“The outstanding scientific discovery of the twentieth century is not television, or radio, but rather the complexity of the land organism,” wrote my father in Round River. As he was hinting, we can locate many of the parts, but how these fit together in the land organism was another matter. Finding the native plant species would be a good start. To reunite some of these came next. The work of our family was creative in its own right: figuring out what conditions these species needed, including by experimentation. Essential to that is appreciating how this landscape got its form—what processes have worked on it and with what results. This much helps us with our understanding of the setting and the soils—what I would call the lay of the land. In the work to restore old habitats and old vegetation types, it is really useful and interesting to know something of the land history, ancient and recent. As Mary Austin wrote, “To understand the fashion of any life, one must know the land it is lived in and the procession of the year.” The Shack experience involved both of these elements. When you live in an area, a natural question that arises is how the landscape got the way it is. What forces shaped it, and over what periods of time? In the Shack area, two different prominent ridges (about twenty-five feet in height) are oriented perpendicular to the Wisconsin River. One is the north-south ridge just west of the Shack—the Sand Hill/Clay Hill ridge. The other is the north-south ridge downstream from Gilbert’s farm; it is the ridge on which the Leopold Center is built. At the point where the river cuts the nose of that ridge (Barrows Bluff) are a great number of large boulders and clay. The Sand Hill site also has an enormous boulder on it. Both have sand on top near the river. I wondered how ridges like these formed in the first place. Then I read the report by Robert Dott and John Attig about the history of the glacial ice lobes in Wisconsin.
