Monument Valley lacks clearly delineated geographical boundaries. It occupies parts of SE Utah & NE Arizona and is near the eastern border of these states. It is within the central part of the Colorado Plateau.

Mineralization is in the Shinarump member of the Chinle formation and the Menkoepi formation. All uranium ore deposits are in symmetric & asymmetric troughs (channels)(62 channels), cut into the Moenkopi formation & the DeChelly Sandstone member of the Cutler formation and are filled with sedimentary rocks.
