"A Geological Map of the United States", Hinton, John Howard

Scarce folding map complete with geological text and engraved geological sections plate. It is an attractive and interesting map that shows geologic formations in color all the way to the Rocky Mountains, here named Chippewayan Mountains, to the east of which is the Chippewayan Desert. Besides the geologic regions, there is quite a bit of information locating Indian tribes and naming waterways in the west. Several hypothetical rivers cross the great basin to the Pacific, holding out the hope of a river passage to the Pacific. The little known map was hand colored only in the London first edition of Hinton's "History." It was compiled from the geological maps of McClure and James (of the Long Expedition) by "several literary gentleman in America and England" who were unnamed, this map marks the last geological map of the US (except for reprints) presented in the Maclurian tradition. It is the first to extend from the Atlantic to the Rocky Mountains. The topographical base is interesting in itself as it shows the Rockies as the "Chippewayan Mountains" flanked on the east by the Chippewayan Desert in Colorado and New Mexico. This edition is unlisted in Marcou or Merrill. The text includes pp. 45 to 104.
