Once again, I am trying to master the process of scanning or copying a map and then getting it into a blog entry. There are just ins and outs of this that I do not understand; hours of frustration. Enough.
This map is from the Arizona map produced by the federal government in 1879. It accompanied the report by the General Land Office to the Secretary of the Interior on S. 1849, the bill introduced by Senator Harrison in 1882 at the request of (in collaboration with?) J. W. Powell. The original proposal was by latitude and longitude, but the GLO changed it to miles measured from the Little Colorado, 56 miles east-west by 69 miles.
When the proposal was resurrected as the Grand Cañon Forest Reserve created by President Harrison in 1893, 17 miles were cut off the top, although it was described once again by latitude and longitude.
The GLO, by the way, referred to the just-proclaimed Yava-Suppai reservation, but did not add it to the map.
A sign of future entanglements is the dashed line of the 40-mile limits of the grant to the railroad, called then the Atlantic & Pacific; what became known as the Santa Fe. The railroad line itself is solid and labelled, though it was still being worked on.
Now that I have Photoshop Elements, I hope to be able to edit and color, to make boundaries more apparent.
The darkish line just north of the 40-mile limit is the fold in the map.
