A remarkably detailed and colorful map depicting, through legend and hand coloring, twenty different geological formations, plus fine detail of roads, post offices, cities, village, roads, etc. A geological survey of New Jersey was conducted 1835-1839 under the leadership of Rogers, the leading geologist of his time. This map was included with his final report. It is also an excellent economic map with a detailed legend at bottom that identifies churches, mills or manufactory, furnace, forge, glass works, taverns, dwelling houses, etc. Lithographed by Duval in Philadelphia. A remarkable map that rarely comes to market.
