National Natural Landmarks
The Little Rockies exhibits excellent exposures of intrusive plugs or stocks with associated sills, dikes and laccoliths, all of which were first studied, described and named there. The mountains have figured prominently in development of the concept of forceful igneous emplacement in relatively flat-lying sediments. It represents the classic site of such formations to geologists around the world.
