Why America's Major Cities Form a Perfect Straight Line

Описание: A satellite map of the United States at night reveals something strange: Trenton, Philadelphia, Wilmington, Baltimore, Washington D.C., Richmond, Raleigh, Columbia, Augusta, and Macon all fall into a nearly perfect straight line stretching over 1,000 miles. Railways follow this axis. Interstate 95 mirrors it mile for mile. This is not a coincidence—these cities are structurally identical twins born of the same invisible parent.

In this video, I explain how the Atlantic Fall Line, a geological seam created by a collision of continents hundreds of millions of years ago, determined where America's most important cities would rise. This line marks where hard Piedmont bedrock meets soft coastal sand, creating waterfalls and rapids on every river flowing to the Atlantic.

For colonial ships, the Fall Line was the end of the road—the head of navigation where cargo had to be unloaded. These "break of bulk points" sparked urbanization: docks, warehouses, taverns, markets. But the same drop that stopped ships also provided power. Water wheels turned the rapids into the 18th-century equivalent of oil fields, grinding wheat and sawing logs.

Even after steam engines and railroads made rivers obsolete, infrastructure has inertia. Railroads connected existing Fall Line cities. Interstate 95 traces the same geological seam. Fiber optic cables follow the rail rights of way. High-frequency trading data travels along paths carved by erosion millions of years ago.
History didn't conquer this geography. It learned to follow it.
