Very detailed and colorful map from A.G. Hager's report. The map was compiled by members of the Vermont Geological Society, which continue operating today. The map has an extensive legend that locates 27 different geological formations though color and pattern. Also locates copper and iron pyrites, ores of iron older than the Tertiary, quarries and mines, and arrows that indicate the strike and dip of the underlying strata. Interestingly, the society printed a different legend and pasted it down over the original. Inset "West Rutland Marble Quarries" locates and names numerous quarries. A most uncommon issue.
