Project Mohole was an ambitious attempt to drill through the Earth's crust into the Mohorovicic discontinuity, and to provide an Earth science complement to the high profile Space Race. The project was initially led by the American Miscellaneous Society with funding from the National Science Foundation. Phase One was executed in spring 1961. Five holes were drilled off the coast of Guadalupe Island, Mexico, the deepest at 183 m (601 ft) below the sea floor in 3,500 m (11,700 ft) of water. This was unprecedented: not in the hole's depth but because of the depth of the ocean and because it was drilled from an untethered platform. Also, the core sample proved quite valuable, showing Miocene age sediments with the lowest 13 m (44 ft) consisting of basalt. Project Mohole contracted with Global Marine of Los Angeles for the use of its oil drillship CUSS I.
