Here the Nottoway River forms an impressive knick zone, dropping ~30 meters (~100′) in less than 1 kilometer (0.6 mi.). A strongly lineated granitic gneiss is well-exposed during low water conditions. The origin of this knick zone is poorly […]

At the Pluton’s Edge
When large quantities of magma intrude and solidify in the Earth’s crust they form bodies of intrusive igneous rock known as plutons. The featured image nicely illustrates the edge (geologic contact) of a granitic pluton in the Blue Ridge Mountains of central Virginia. The granite is part of the 706 ± 4 million year old […]
