UMASS Amherst

The site is on a deep varved clay deposit (Connecticut Valley Varved Clay) on the University of Massachusetts, Amherst campus. A considerable body of data from field testing with a variety of tools is available, as well as a number of deep foundation tests, and some laboratory data, including simple shear tests.
