The true and correct factual information is that the St. Francois Mountains are the oldest mountains in North American. The Appalachians and Rockies are mere babies comparatively. As for the Black Hill, well, they are just that .....hills.
The Appalachians began forming 460 MILLION years ago.
The Saint Francois Mountains of Missouri were formed 1.4 BILLION years ago.
The Black Hills are dated to 1.8 Billion years ago with some of the rock being dated from 2.2 to 2.8 Billion yearsold.
Much research has been done in the St. Francois mountains of South East Missouri. They have been considered the oldest range by many geologist. Volcanic episodes created many unique, beautiful, and odd formations throughout this mountain range which is located within the Ozark Plateau. The Precambrian exposures of Pilot Knob are regularly studied by geologist from around the world. The draw to these exposure's seem to be that they are found only in two places around the world, at Pilot Knob Missouri in Iron County and in New Zealand. Elephant Rocks and Johnson Shut-ins are two more examples of strange and unique results of geological events. The area is rich in geological formations and is very secluded which makes this a favorite site of geologist, hikers and other outdoor enthusiasts.

The mountains with the OLDEST ROCKS is most likely the Appalachian Mountain Range along the eastern edge of Canada and the USA.
