Near Marathon in Brewster County, Texas — The American South (West South Central)
(In Core of the Ouachita Structural Belt)
The northwesterly trending Del Norte-Santiago range (southmost extension of the Rocky Mountains) forms the southwestern skyline. The rocks of this range were deposited in a sea that covered the Ouachita Fold Belt after erosion had reduced the highlands and a later submergence lowered the area. Santiago Peak (named for a local man who was killed by Indians and buried beneath the peak) is the high, flat-topped mountain to the southwest. It was once a mass of molten magma that cooled and hardened underneath the earth's surface and was uncovered by later erosion. The Del Norte-Santiago range, uplifted and folded 40 to 60 million years ago, is not half the age of the Ouachita Fold. This is a remarkable fusion of "old" and "young" mountains—and
Erected 1970 by State Historical Survey Committee. (Marker Number 3124.)
