The Soils of Putney Vermont
The town of Putney is situated in the south eastern corner of Vermont, in the Connecticut River Valley. Although the town occupies just 26.8 square miles, the diversity of its soils is remarkable. The variation of Putney’s soils has led to a wide range of land uses depending on the soil type, and its position on the landscape. By exploring the factors that contributed to the formation of Putney’s soils, and by discussing the characteristics of those soils, this paper will explain the significance of the town’s land use. Much of the diversity of Putney’s soils can be attributed to the movements of the Laurentide ice sheet that, 20,000 years ago, covered the region in several thousand feet of ice. As the glaciers proceeded south, they reconfigured the land’s surface layer by scraping away the existing soil. As the world’s climate warmed, the ice retreated, redepositing glacial till across the landscape. Topography played an integral role in the distribution of soil following glaciation. In the hills, this unsorted till, a collection of boulders, cobbles, gravel, sands, silt, and clay, began the slow process of pedogenisis (soil formation) as plants and animals brought life to this barren world. In the valleys, material was sorted by the water from the melting ice as it flowed down from the hills (Stewart 55). Below, in figure 1, the areas of unsorted till are represented in orange while areas of sorted sediment such as gravel, sand, outwashes,
