Description:	Technical Report Abstract: This report documents a mechanical property investigation conducted for Sandia National Laboratories, Livermore (SNLL) on undisturbed soil specimens obtained from a site at Antelope Lake within Tonapah Test Range near Tonapah, Nevada. The purposes of the investigation were to experimentally determine the mechanical responses of the Antelope Lake specinens and to provide representative material properties to SNLL. The completed laboratory test program obtained mechanical property data from 6 static unconfined compression tests and 12 static triaxial compression tests. In addition, composition property data in the form of water content, density, void ratio, etc., were obtained for the materials investigated. The failure strengths of materials at the Antelope Lake site were found to be dependent upon the initial degree of saturation of the test specimens and the magnitude of the applied mean normal stress. Clays from Layers 1 and 3 became fully saturated at a mean normal stress of about 14 MPa and achieved a Mises limiting strength of 5.3 MPa. The silts and silty sands in Layer 2 became fully saturated at about 3.4 MPa mean normal stress and achieved a 2 .5 MPa Mises limit.
