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.
