Based on decades of research and written in clear, concise prose by one of the foremost geographers in North America, John C. Hudson's Across This Land is a comprehensive regional geography of the North American continent.

Clearly organized, the book divides the entire United States and Canada into six major regions, then further subdivides them into twelve smaller areas. Hudson emphasizes each region or area's distinguishing place-specific attributes, including—to a larger degree than previous regional geographies—political considerations. In this way, the book tells the story of each region, relying on a brisk narrative that reveals the dynamic processes of their distinctive characteristics.

The first extensive regional geography of the North American continent in over seventy-five years, Hudson's Across This Land will become the standard text in geography courses dealing with Canada and the U.S. as well as a popular reference work for scholars, students, and lay readers.
