Ogden Tweto (1912 - 1983) created the now-classic Geologic Map of Colorado [1] which is held as one of the finest examples of a state geologic map. [2]Tweto received awards including the Distinguished Service Award of the Department of the Interior (1970) and the Scientist of the Year Award by the Rocky Mountain Association of Geologists (1978).

The Colorado Province took shape as a mobile belt—an area of thinner, orogeny related continental crust lacking the deep "keel" of rock, which stabilized the neighboring Wyoming Craton and other cratons like it. Throughout Colorado's geologic history, rocks have often been deformed, metamorphosed and overprinted, obscuring the ancient record.
Colorado is a geologic name applied to certain rocks of Cretaceous age in the North America, particularly in the western Great Plains.. This name was originally applied to classify a group of specific marine formations of shale and chalk known for their importance in Eastern Colorado.
