THE CITY OF COZAD is located where the 100th meridian crosses the Lincoln Highway. Moreover, this otherwise typical Midwestern town is unique because it stands at the edge of Nebraska's Great Plains. Historically the town gained importance as a Pony Express stop in the 1860s and, of course, the Transcontinental Railroad came through here as it was constructed along the Platte River westward to meet the Central Pacific Railroad in Provo, Utah.
The 100th meridian is the longitude line extending between the earth's north and south poles passing through North America, the Pacific Ocean, and Antarctica. And it happens this line is more than a "round" number that map cartographers marked from Greenwich, England. The meridian identifies the climate boundary where moist air generated from the Gulf ends, the semi-arid western prairies begin, and the humidity from the eastern seaboard increases. West of the 100th meridian, crops rely heavily on irrigation to survive the summers -- but not throughout the east. So now I'm entering the land of hurricanes, tornadoes, and persistent storms.
The 100th meridian also denotes the boundary between the eastern and western United States. And finally -- on a personal note -- this marks 1470 miles of my virtual walk across the USA. I've traveled halfway across the country and my goal to reach the eastern seaboard is now a true reality. And it's just the first week in May!
