Alternate Drainages
Imagine U.S. History With No Missouri River U.S. buys a much smaller Louisiana Purchase No easy water route for Lewis and Clark No claim to the Pacific Northwest by right of discovery Oregon, Washington, Idaho, Montana and the Dakotas might be part of Canada No gold rush to the Black Hills or war with the Lakota? Or maybe war with Great Britain?
If there’s even a United States, that is…..
Diversion of the Ohio
Possible Pre-Pleistocene Rivers
Imagine U.S, History With No Great Lakes No water route into northern interior No Erie Canal No Buffalo, Toronto, Cleveland, Detroit, Milwaukee or Chicago
Imagine U.S, History With No Ohio River Only access to the Mississippi is over the southern Appalachians and much harder Economic center of gravity in mid-Atlantic states? Commerce west of Appalachians runs north into Canada (maybe still French?) United States hemmed in along Atlantic Coast Why purchase Louisiana?
If There’s Even A Great Britain, That Is…
Pre-Pleistocene Europe
Cutting the English Channel
Alternate Europe
