Land and Property
- California Trail 1844 to 1869 from western Missouri to northern California
- Carson (River) Trail 1848 (aka Mormon Emigrant Trail) crossed the Forty Mile Desert past the west side of the Carson Sink to pick up the Carson River near Fallon, Nevada up to Hope Valley and Red Lake. The Devil's Ladder then climbed 700 feet (210 m) in half a mile so ropes, chains, and pulleys were required to lift the wagons. Carson Pass was followed by the relatively easy West Pass (Kirkwood, California) and then on to Pollock Pines, Placerville, and Sutter's Fort, California
- Big Tree Road (Ebbetts Pass) 1851 from western Nevada to Markleeville, Murphys, Sonora, and Stockton, California
- Sonora Road 1852-1854 from the Carson Trail south to the Walker River along the base of the Sierra Nevada until it ascends to Sonora Pass and then down to Strawberry and Sonora, California
