註釋The geology of the area near Black Mesa State Park and northwestern Cimarron County is unique in Oklahoma. Nowhere else in the State are Triassic and Jurassic rocks exposed, except for some small exposures of Triassic rocks near Guymon. Nowhere else in the State have so many dinosaur bones been discovered; so many, in fact, that they are only now being properly catalogued and identified. And nowhere else in the State is there evidence for recent nearby volcanism; Black Mesa, the highest point in Oklahoma at 4973 ft above sea level, is a basalt lava flow that is less than 5 million years old and was erupted from a volcano located in southeastern Colorado.; In addition, the physiography of this part of the Panhandle is completely different from that in the rest of Oklahoma. For the traveler arriving from the east, the seemingly monotonous "flat" of the High Plains suddenly gives way to buttes and mesas reminiscent of "The Old West". This change is physiography is a direct result of the unique geology of this corner of Oklahoma.
