What some consider Nevada's first Euro-American town appeared in the Carson Valley in 1850. Gold Rush fever had swept the nation, sending fortune-seekers streaming into California. The Humboldt Trail, one route west, crossed Northern Nevada and deposited prospectors at the foothills of the Sierra Nevada. At this point a handful of Mormons established a trading post to provision road-weary travelers. Their success and the Comstock Lode's discovery soon attracted others, but Genoa and Dayton now competed for the title of the first American settlement in the western Great Basin.
