232.Making of the West
Even before the Revolutionary War explorers and settlers had crossed the Alleghany Mountains . In Washington ' s time pioneers , leaving Pittsburg , floated down the Ohio River in flatboats . Some of these settled Cincinnati . Others went farther down the river to Louisvile , in Kentucky , and still others founded Wheeling and Marietta . In 1811 the first steamboat appeared on the Western rivers . The whole prob - lem of living in the West rapidly changed . For the steamboat could go up stream as well as down stream . communication between the new settlements , and New Or - leans and Pittsburg , was now much safer and very much easier .
