About this map

Salt Spring Valley and the Nassau Valley define the landscape of this portion of Calaveras County, where cattle ranching and early mining heritage have left a distinctive footprint. The map documents the rural character of the area, punctuated by small settlements like Felix, Carmen City, and the intriguingly named Lost City. These outposts are connected by a network of ranch roads and trails with names that reflect the region's equestrian and frontier history, such as Jaquima Dr, Tapadero St, and Bonanza Mine Way.

The terrain is dominated by the Bear Mountains and prominent peaks like Mt Ararat and Copperopolis Mtn. Water sources are vital in this Mediterranean climate, with drainage provided by Littlejohns Cr and Salt Cr, alongside features such as Gooseberry Spring. Researchers can trace the modern boundaries of the Public Land Survey System while identifying geographic landmarks like Heiser Canyon and the Big Seven Ridge that shaped the movement of early settlers and miners through this section of the Mother Lode region.
