Publisher's Synopsis
Excerpt from The Physiographic Features of Maryland
The State of Maryland extends from, approximately, the 75th. Meridian to west longitude 79� It thus embraces within its' boundaries portions of the Atlantic Coastal Plain, the Piedmont Plateau, and the Appalachian Ranges and Plateau, the three geo logic and geographic provinces of the Atlantic slope of North America. The state may, therefore, be said to present in its own varied topography, an epitome of the surface features of the whole Atlantic slope. Oi these three provinces, the Piedmont plateau is the oldest. This is shown both by comparing its highly metamorphosed crystalline and sedimentary rocks with the relatively unaltered strata of the other provinces, and by the character of its topog raphy. From the Piedmont, in early geologic time, were obtained the materials which are now found built into the folded and faulted strata of the Appalachian regions. From both Pied mont and Appalachian districts 9. Great volume of sand, gravel, clay and boulders, has been washed during the later periods of geological time. These materials are now found forming the youngest of Maryland's topographic provinces, namely, the Coastal Plain. These three provinces, with their several subdivisions, are shown on the accompanying map. (fig. In the following pages the characteristics and the development of the chief surface features of these provinces will be briefly discussed.
