With miscellaneous geographic information concerning areas, altitudes, and geographic centers.

With the exception of oceans, boundaries are artificial, man-made divisions of geography that many times make little sense and sometimes no sense at all. For example, why does the northern boundary of Minnesota protrude into Canada? Why does West Virginia have two panhandles? Why do Pennsylvania and Delaware have a common boundary that is a circle segment? Why do the boundaries of Colorado, Wyoming and Utah consist entirely of lines of latitude and longitude? The answers to these questions and many more can be found in this book, which explains why and how state boundaries are placed where they are. It begins with an introduction that provides general information about boundary placement, colonial boundaries, formation of territories, surveying and Supreme Court rulings. The 50 states are divided into ten regions (New England, Mid-Atlantic, Upper South, Lower South, Great Lakes, North Central, South Central, Rocky Mountain, West, and Noncontiguous). The text for each state begins with an overview of that state's boundaries that becomes more specific as its different boundaries are considered. The appendices include interesting facts about each state, citizen and state nicknames, and dates territories were created and states entered the Union. Richly illustrated with 138 maps.
