Yucca Flat is a closed desert drainage basin, one of four major nuclear test regions within the Nevada Test Site (NTS), and is divided into nine test sections: Areas 1 through 4 and 6 through 10. Yucca Flat is located at the eastern edge of NTS, about ten miles (16 km) north of Frenchman Flat, and 65 miles (105 km) from Las Vegas, Nevada.[2] Yucca Flat was the site for 739 nuclear tests – nearly four of every five tests carried out at the NTS.[3]
Yucca Flat has been called "the most irradiated, nuclear-blasted spot on the face of the earth".[2] In March 2009, TIME identified the 1970 Yucca Flat Baneberry Test, where 86 workers were exposed to radiation, as one of the world's worst nuclear disasters.[4]
