Geology and Soils
The bedrock of the Park consists of Precambrian to Ordovician period quartzite and slate, plus Devonian period granite. All of these rocks, especially quartzite, have a high silica content and provide scanty amounts of nutrients to the soils that develop on them. The slate, however, is fine-grained and produces a loamy soil which yields its nutrients more quickly than the stony sandy loams and loamy sands found over the coarse-grained rocks. Most of the slaty loams occur around Kejimkujik Lake. Deep outwash sands and gravels form a band west of the lake. Elsewhere the soil landscape is dominated by the cobbly, often shallow granite or quartzite material. Podzols underlie most well-drained areas. Gleysols and peat bogs dominate where drainage is poor. The Park receives acid rain, and its soils have few available acid-buffering minerals, so strong acidity is the rule for soils and waters—even large bodies of water such as Kejimkujik Lake.

Famous quotes containing the word soils:
“He bends to the order of the seasons, the weather, the soils and crops, as the sails of a ship bend to the wind. He represents continuous hard labor, year in, year out, and small gains. He is a slow person, timed to Nature, and not to city watches. He takes the pace of seasons, plants and chemistry. Nature never hurries: atom by atom, little by little, she achieves her work.”
—Ralph Waldo Emerson (18031882)
