A Separately Published Map Depicting New York’s Geology
New York State/ Geology.
SHERMAN & SMITH [New York, 1842]
Geological Map Of The State Of New York By Legislative Authority. .
35 x 35 ½ inches
Fine original wash color; expertly conserved—re-mounted on new linen; lightly toned, filled nail holes along top and bottom not affecting printed surface, else fine.
A scarce, elegantly presented, small wall map showing by means of colors the various geological zones of New York State. Along the right 19 different types of surfaces, many classified according to the prevalent rock or stone, are listed with each assigned a different color corresponding to the map. At bottom left are four fascinating profile views, each of which transverses entire state in different directions. Elevations are depicted in the profiles, and their geological composition is identified. Although the map’s title states that it was published “By Legislative Authority,” there is no indication it was a governmental publication.
