A study was made of a recent landslide along a newly opened, relocated section of U. S. Route 50 in Vinton County, Ohio. This segment of highway is located in the abandoned valley of a minor tributary of the Teays River system. The investigation revealed that a highly laminated lake deposit was the major component of the slide. Mineralogical and particle-size determinations show that this material is an extremely fine-grained, illitic clay having characteristics similar to those of the Minford Silt. Several of the physical properties determined in this study suggest that this type of deposit is likely to become unstable wherever disturbed by heavy construction and, since material of this type appears to be widespread in the valleys of the Teays drainage system, such deposits should be given special attention by design engineers.
