The McDermitt caldera complex is a Miocene collapse structure consisting of nested and overlapping calderas. The calderas occur along the Nevada-Oregon border about 320 km southwest of Boise, Idaho, and 380 km northeast of Reno, Nevada. Two uranium deposits occur within the complex -- the Aurora and Moonlight deposits. Numerous occurrences of uranium are localized in ash-flow tuffs, moat-fill sediments, and ring domes and intrusives.
