Jackpile mine, looking north, around 1980. The Jackpile-Paquate open pit mine was discovered by aerial reconnaissance in 1951 and closed in 1983. It was the largest uranium mine at that time, consisting of 4 coalescing pits. The mine complex produced more than 80 million pounds of U3O8 from the Jackpile Sandstone of the Morrison Formation. The Jackpile-Paquate mine is now an EPA Superfund site. W.L. Chenoweth photo.
