Landslides in the Presumpscot Formation: An engineering study

PDF versionPDF version


Publication Year: 



Many landslides in Maine have occurred in the marine clay, called the Presumpscot Formation, which covers much of southern Maine. This glacially derived clay was deposited in the sea during the retreat of the late Wisconsinan ice sheet, and subsequently was uplifted by crustal rebound after the glacier receded. Most of the landslides are single rotational slides, but some of them comprise a number of slides formed by retrogressive slope failure. The retrogressive slides are potentially the most destructive, since they occur rapidly with little apparent warning and cover a large area.
