Although this was one of the first units to be recognized in the area (Hills, 1888), it was among the last named (Johnson and Wood, 1956a). The age of the Devil's hole formation is PPliocene. This age determination is based upon horse and camel teeth found by R. C. Hills in the area between Muddy and Turkey Creeks (1889, p. 220-221). Hills did not send the fossils to O. C.

C. Marsh, dated 26 October, 1889). I do not know where these specimens are now stored. Structural Geology General Statement. Three features determine the basic structure of Huerfano Park: The Greenhorn (Wet Mountains) Anticline, the La Veta Syncline, and the Sangre de Cristo Complex of folds and faults. Minor folds, faults and intrusions are related to the major structure. In east-west profile, the Colorado Rockies are characterized by an eastern anticlinal mountain range (Front Range, Wet Mountains) occupying the site of the Paleozoic Colorado Mountains (King, 1959, p. 104, 105, 118); a structural and depositional basin west of the anticlinal mountains (North-Middle, South Parks; Wet Mountain Valley-Huerfano Park) and a western mountain range or ranges (Northern Sangre de Cristo, Sawatch, Mosquito, Park) which generally has major thrust fault zones and can have a thick section of late Paleozoic rocks making up much of the range (Sangre de Cristo, Mosquito). The syncline and the western.
