Botanical prospecting for uranium is a method of finding uranium deposits either by observation of plant life growing on the surface, or by geochemical analysis of plant material. The history of uranium prospecting, especially in the Colorado Plateau of North America, has seen several methods of identifying likely ore body locations. The use of radiation detectors, such as Geiger counters and scintillation counter is one such method. Another method widely used relies on knowledge of the geologic history of an area, such as locating a geologic formation known to host ore deposits.
