The paper describes observations of the travel times from a series of 5-ton shots fired by the United States Geological Survey in Lake Superior during July 1966 Project Early Rise. The observations were made along three profiles the Wichita profile, extending 2250 km from Lake Superior to the Texas-Mexico border, the Little Rock profile, extending 1650 km from Lake Superior to the Arkansas-Louisiana border and an arc profile at a radius of about 1200 km from the shot point from West Virginia to the Kansas-Nebraska border. These records and others of the nuclear explosion GREELEY at points in the central United States, taken in conjunction with the times for GNOME, have been analyzed and model calculations made. Author
