The site of the Flivver experiment is in basalt on the central ridge of Buckboard Mesa, Nevada Test Site. A soil layer averaging 2 feet thick covers the site. The basalt, which is about 237 feet thick at the Flivver site, can be divided into three units an upper, vesicular unit a middle, dense unit and a thin, basal vesicular unit. Deformation of vesicles and concentration of vesicles into layers during viscous flowage have imparted a pronounced layering to the basalt. The orientation of these layers indicates that the major structure of the ridge is cylindrical. Minor folding in the upper portion of the flow complicates this structure. The trend of the ridge and the attitudes of flow layers indicate that the flow curved eastward as it flowed south-southeast across the site. Author
