Maps showing GCNP and the Kaibab National Forest north and south of it as depicted here would have been much the same since the Park was created in 1919. Grand Canyon National Monument (the second) was a 1930's creation. Lake Mead N.R.A. dates from 1964. The boundary shown here, including the northern portion of the Hualapai Reservation, is incorrect. The Hualapai rejected being included, having their own ideas (see the Sep 27 entry about the visionary, Mahone). The Havasupai Reservation was still miniscule, and although the dam fight was not concluded, the damsites are not shown. Other road maps were not so bashful, like the Shell map I remember from that time, with Bridge damsite a strong black mark across the river. However, Bridge Canyon is labelled, just south of the word "AREA" in the western Canyon.
That was the map we faced and were used to. Insofar as the Grand Canyon is a human concept of a natural construct, it was quite constricted, having no beginning and no ending, its river split among seven jurisdictions, mostly open to exploitation. GCNP and the Kaibab NF represented the pared-down vision of Powell, the pink Park defining, for almost everyone, the Grand Canyon as a spectacular "hole finally giving us a place to dump all our used razor blades in" -- I think thats from Frank Waters' book on the Colorado.
