This is a paleoliquefaction site under current study by Martitia Tuttle, Laurel Clark, and Buddy Schweig.   Evidence of liquefaction by presence of sand dikes has been investigated by geologists using trenching & mapping methods.  Several series of vertical resistivity piezocone soundings were conducted in linear arrays away from two large dikes found at the property.
