The Sedan nuclear crater is located at the Nevada Test Site, about 90 miles north of Las Vegas.

The intensity and distribution of radiation, however, proved too great, and the program was abandoned.

Operation Plowshare resulted in 27 thermonuclear detonations.

Only four events were intended to produce craters, among which Sedan was by far the largest.

The resulting crater is 100 meters deep and 390 meters wide.

An observation platform built on the rim of the crater allows tourists to peek into the crater below.
