West of the 100th Meridian


John Wesley Powell believed that the 100th Meridian was the dividing line between the American East and West. 100 wasn't just a convenient number, it also represented the approximate boundry of which lands to the east received more than 20 inches of rainfall and lands to the west received less. These photographs, all taken at or west of the 100th Meridian, examine "The West" as delineated by John Wesley Powell.
