The legend shows nine different surveying efforts, 7 of which were federal projects with the other 2 being the New Hampshire and New Jersey Geological Surveys. Included with the map is Powell's 72 pp. report, disbound.
Map is clean and bright with a fold separation that extends 0.75" beyond the neatline at top, minor damp stains in the top blank margin that extend just past the border along two folds, and a few ink smudges at far right.
