What river did Mark Twain pilot steamboats on?

Mark Twain piloted steamboats on the Mississippi River.

Born Samuel Langhorne Clemens, Twain grew up in Hannibal, Missouri, a Mississippi port where steamboats were central to commerce and daily life. In 1857, he became an apprentice, or “cub,” pilot under Horace E. Bixby. He studied the river’s constantly changing channels, reefs, snags, currents, and landmarks between St. Louis and New Orleans.

Twain’s river experience later became the foundation for Life on the Mississippi, his 1883 memoir and travel book. The work combines personal recollection with a history of the river, observations about changing transportation, and vivid descriptions of steamboat culture.

A common mix-up is confusing Twain with pilots who worked on the Missouri or Ohio rivers. He did travel and work in several parts of the United States, but his famous piloting career—and the source of his pen name—was tied specifically to the Mississippi. “Mark twain” was a leadsman’s call indicating two fathoms, or twelve feet, of water.
