Physiographic Map of Maryland
Maryland is part of six distinct physiographic provinces: (1) the Atlantic Continental Shelf Province, (2) the Coastal Plain Province, (3) the Piedmont Plateau Province, (4) the Blue Ridge Province, (5) the Ridge and Valley Province, and (6) the Appalachian Plateaus Provinces. These extend in belts of varying width along the eastern edge of the North American continent from Newfoundland to the Gulf of Mexico.
The Physiographic Map of Maryland consists of 2 sections. The first section is Explanatory Text for the Physiographic Map of Maryland (Open File Report 08-03-1 ). This publication has detailed information on the physiographic provinces and subdivisions, 6-digit code used on the map, a summary of topography and geology of ridges in the Ridge & Valley Province and much more. The second section is "Plate 1. Physiographic Map of Maryland (scale 1:250,000)", the PDF map file. This publication is available for download in PDF format. The current version, MDPHYS2003.2, is published September 2008.
