Jacob J. Marklee founded a toll bridge crossing the Carson River in 1861. He aimed to tap into the traffic from the silver mining boom at Silver Mountain City. On June 23, 1862, he recorded a land claim of 160 acres in Douglas County, Nevada. A boundary survey took place, and the property ended up being in California. In 1863, Marklee died after being involved in a gunfight. When the Comstock Lode discovery took place, the town of Markleeville was founded on the Marklee property. Today, the Alpine County Courthouse sits on the former property, which is listed as a California Historical Landmarks.
A post office opened in Markleeville in 1863.
