What was the title of Mark Twain's travel book about the American West?

Mark Twain's travel book about the American West was Roughing It. Published in 1872, it is a semi-autobiographical account of Twain's travels and adventures in the western United States during the 1860s.

Twain traveled west with his brother, Orion Clemens, who had been appointed secretary of the Nevada Territory. The book draws on Twain's experiences in Nevada and California, including prospecting for gold and silver, real-estate speculation, a visit to Salt Lake City, and his early work as a newspaper writer. It also includes an account of his journey to Hawaii.

Roughing It is often confused with Twain's other travel books. The Innocents Abroad, published in 1869, describes a voyage through Europe and the Holy Land, while A Tramp Abroad covers a later journey through Europe. Life on the Mississippi focuses primarily on Twain's experiences with the Mississippi River and its pilots. Roughing It is especially notable for blending travel memoir with tall tales and the comic exaggeration that became central to Twain's literary style.
