Geology
The Adirondack Mountains form most of northern New York state. They are an uplifted complex of Precambrian metamorphic rocks - like the Llano Uplift in Texas, a part of an ancient (Grenville) continental province. The Paleozoic sedimentary strata that now flank these older rocks once covered them. The intersecting faults and joints responsible for the rectilinear surface texture of the Precambrian rocks developed from release of pressure on this once deeply buried metamorphic complex. - USGS
