A yellowcake boomtown also known as a uranium boomtown, is a town or community that rapidly increases in population and economics due to the discovery of uranium ore-bearing minerals, and the development of uranium mining, milling or enrichment activities. After these activities cease, the town "goes bust" and the population decreases rapidly.[1][2][3]
Yellowcake (uranium oxide) is partially refined uranium ore, called so because of its bright yellow color.[4]
Jeffrey City, Wyoming is considered a yellowcake boomtown whose "boom" began in 1957, and by 1988 the town had gone "bust" with only a few residents left.[4]
