Biotechnical Soil Stabilization of Decomposed Granite Soils on Buckhorn Mountain

摘要

Over the last 20 years there have been many efforts at discovering techniques for erosion control and slope stability in the severely decomposing granitic soils of Buckhorn Mountain. Buckhorn Mountain is an exposed decomposed granite (DG) batholith, at a 2000-3000 foot elevation, that separates Shasta and Trinity Counties in Northwestern California. Westbound State Route 299, which serves as the main arterial between the Northern Sacramento Valley and the Northern California Coast, traverses Buckhorn Mountain for almost 15 miles over steep mountainous terrain.
