The Bombarded 38' Parallel
August 2002 by Edgar B. Heylmun, PhD
A 1,200-mile long east-west zone, containing unusual geologic features, has been recognized in the eastern half of the United States for over 100 years. It coincides, in a general way, with the 38° parallel. There are as many opinions on the origin of the features as there are geologists. Most of the features are circular or oval in form, and some are concealed by younger rocks. They are found in 8 states, from Kansas east to Virginia.Additional articles that might interest you...

The River Runs Through It
September 2002
Why couldn’t we take some cold river water, pass it through some cooling coils and cool the air in the mine? This thought came to me one Sunday afternoon while fishing, knee deep, in the cold Coeur d’Alene River just west of Kellogg, Idaho.
