Though the Colorado Plateau is generally floored with horizontal or slightly inclined sedimentary strata, its surface has been roughened in places by folding, faulting, the building of volcanoes, and the intrusion of igneous rocks—geologic activities that have modified the otherwise normal drainage pattern and the orderly development of erosion features.

 Summary of December 1999 Meeting of the New England Botanical Club
The Colorado Plateaus define the southeastern portion of the state while the southwestern corner is considered an eastern extension of the Mojave Desert floristic province.
A western fifth of the state consists of the Great Basin (formerly occupied by the Pleistocene Lake Bonneville) and 35 associated mountain ranges including the calcareous Wasatch Mountains that form the Basin's eastern border.
This leaves one or more provinces in the east that include the Uinta Mountains with floristic affinities to the Rocky Mountains, the Uinta Basin, considered by some to be part of the Colorado Plateaus, and the La Sal Mountains along the border with Colorado.
