Twain joined his brother, Orion, who in 1861 had been appointed secretary to James W. Nye, the territorial governor of Nevada, and headed west. Twain and his brother traveled for more than two weeks on a stagecoach across the Great Plains and the Rocky Mountains, visiting the Mormon community in Salt Lake City along the way. These experiences inspired Roughing It, and provided material for The Celebrated Jumping Frog of Calaveras County. Twain's journey ended in the silver-mining town of Virginia City, Nevada, where he became a miner. Twain failed as a miner and found work at a Virginia City newspaper, the Territorial Enterprise. It was here that he first used his famous pen name. On February 3, 1863, he signed a humorous travel account "Letter From Carson – re: Joe Goodman; party at Gov. Johnson's; music" with "Mark Twain"
