Dekalb soil and landscape
Soil profile: Dekalb very channery loam. This Dekalb soil, which formed under forests, has dark organic horizons at a depth of 0 to 10 centimeters. Dekalb soils have bedrock at a depth of 50 to 100 centimeters. In this photo, bedrock occurs at a depth of approximately 70 centimeters. (Soil Survey of New River Gorge National River, West Virginia; by Wendy Noll and James Bell, Natural Resources Conservation Service)
Landscape: An area of a Layland-Dekalb-Rock outcrop complex, 55 to 80 percent slopes, extremely stony. The extremely stony Layland soil is in the foreground, and the Dekalb soils and Rock outcrop are in the background.
