Question from Bramleys' "The Gods of Eden"

[bltay]

I hope I have placed this in the right place. Although The Gods of Eden may be considered a religious topic my question pertains more to history.

William Bramley The Gods of Eden pages 368-369:

In his first books, Mr. Ballard claims to have visited four secret underground locations altogether: two of them while “out of body” and two by regular human means. Interestingly, each location corresponded to a region in which there existed earlier in history a major civilization worshiping the Custodial “Gods.” The Teton location coincided with the ancient North American civilizations. A similar underground location in South America went hand-in-hand with the Incan civilization on that continent. A trip by boat and automobile resulted in a stopover at a reputed underground location on the Arabian peninsula, which matched the ancient Mesopotamian and Egyptian civilizations. The fourth location in the mountains above the city of Darjeeling, India, corresponded to the ancient Aryan civilizations of the Indian subcontinent.

Having done some extensive hiking in the Teton Mountains, I found this quite interesting. I am familiar with the ancient civilizations referred to in all of the places namned except the Teton Mountain area. There are no ruins/remnants of any ancient civilization in that area that I know of and have not been able to locate any references to ancient civilizations there. Does anyone know of any ancient civilizations in this area?
