A fall line is the site between an upland region of continental bedrock and an alluvial coastal plain. A fall line is particularly important where a river crosses it, as this is often the point where a river can't be navigated due to the presence of rapids or falls. In the early industrial age, this point on a river was also important as it often provided the ideal location for water-wheel driven mills and factories. The two factors combined made for the almost guaranteed growth of towns and even cities where rivers crossed a fall line along the east coast of North America.
