Paperback. Etat : New. Print on Demand. This book is a comprehensive analysis of the geology of Armstrong County, Pennsylvania. The author has conducted detailed surveys of each valley and watershed in the region and describes the geological makeup of the area in detail. The book also provides railroad and oil pipe-line level data to illustrate the county's topography. The author notes the presence of valuable re and pot clays, building and ag stone outcroppings, and local occurrences of iron ore and limestone. However, he also notes the abundance of large fallen stone blocks that make much of the land unsuitable for agriculture. The author additionally discusses the presence of two distinct coal groups within the Pottsville Conglomerate, which challenges the conclusions of previous geological surveys in the area. The book concludes with a discussion of erosion and drainage systems in the county.
