I guess then, that the mountain roots in southern Oklahoma that we refer
to as the Arbuckle mountains are reeeeally mature. Those mountains saw the
dinosaurs come and go and the southern 5 miles of the range were cut into
a plain by the surf of the sea that covered parts of Oklahoma and Texas at
the time.


3.7 BILLION year old rocks can be seen (walked on, touched) in Voyageurs
National Park, Blue Mound State Park and other places around Minnesota.
These are some of the oldest rocks on the planet. Dinosaurs - Ha!
