The glaciers that swept down over the northern states in the Quaternary have removed many of the Tertiary deposits in North America. In other places around the continent, exposures of Tertiary rocks are very common. Large exposures can be found in the U.S. along the Atlantic and Gulf Coasts, Great Plains, Rocky Mountains, Great Basin, Cascade Mountains, and Olympic Peninsula. Tertiary exposures are also bundant in Western Mexico and the Yucatan, as well as in several western Canadian provinces.
