This original antique coloured lithograph plate depicting a cross sectional geological part view of the New York and Harlem Railroad and the Park Avenue or Murray Hill Tunnel by the Endicott company, was published in the 1842 edition of William Mathers Geology of New York

The view depicts about 400 yards of rail in two views, a north view and a south view. Each view is split into approximately equal distances of 200 yards each. In the views, the cross section of the ground through which the tunnel was cut is illustrated, comprised mostly of layers of diluvial loam and gneiss. Some granite veins run through the gneiss, which are colored red.

Measures approximately 18.5"x11.5"

In good condition, original piece!
