Reading Prong

The Reading Prong is a physiographic subprovince of the New England Uplands section of the New England province of the Appalachian Highlands. The prong consists of mountains comprised of crystalline metamorphic rock.

Location

The Reading Prong stretches from near Reading, Pennsylvania, through northern New Jersey and southern New York, reaching its northern terminus in Connecticut.

Near the Hudson Valley, the term Hudson Highlands is often used. The portion of the prong that enters Connecticut is known as the Housatonic Highlands.

Relation to other divisions of the New England Uplands

In addition to the Redding Prong, there are two additional subsections of the New England Uplands. A prong of the same rock belt extends from the Hudson Highlands south to New York City along the Hudson River. This region is often referred to as the Manhattan Prong. The Staten Island Sepentinite is also a southward extension of the New England Uplands.

Geology

The Reading Prong is part of the Precambrian basement which is discontinuously exposed in the north-central Appalachians. The rocks that make up the prong consist of diverse gneisses.

In the gap between the Blue Ridge and the Reading Province, the two mountainous regions descend into the Appalachian piedmont. Together, the Blue Ridge province and the New England province are often referred to as the Crystalline Appalachians. Rocks of the Reading Prong are characterized by elevated concentrations of Uranium. Decay of this Uranium produces gaseous Radon, a potentially hazardous source of indoor contamination in structures constructed on the prong.
