Show Appendix G EXCERPT FROM NATIONAL PARK SERVICE STATEMENT ON CRSP, IN 1950 RECLAMATION BUREAU REPORT Dinosaur National Monument was established by procla- mation of President Wilson on October 4, 1915, under authority of the Antiquities Act for the primary purpose of preserving a rich deposit of fossilized dinosaur bones which had been found here in an excellent state of preservation. By President Roose- velt's proclamation of July 14, 1938, the monument was en- larged to include other resources of geological, archeological, and wilderness values. The extension included the canyon of the Yampa River and the Canyon of Lodore, Whirlpool Can- yon and Split Mountain Canyon on the Green River. Of the total gross area of 209,744 acres, about seventy per cent is in Colorado and about thirty per cent in Utah. The enlarged monument is essentially a canyon-plateau area along the most spectacular and scientifically interesting parts of the drainage of the Green River and its major tribu- tary, the Yampa. The dynamic processes of river erosion have produced a colorful, rugged wilderness of deep canyons, dis- sected erosional benchs, and bold promontories. The geologi- cal features have been given the place of outstanding import- ance. Second to these are the scenic features which form an in- separable combination with those of geology. Functionally, Dinosaur National Monument consists of two sections referred to as the quarry section and the canyon section. The quarry section comprises a comparatively small area in the vicinity of the dinosaur beds and includes the original monument. The canyon section, consisting of the remainder of the present monument, is over 200,000 acres in extent. The geologic formations of the quarry section are of scientific importance and of distinct scenic value, but the major signifi- cance of this section is considered to be in the dinosaur beds. The principal deposits of fossilized dinosaur bones are found |
