About this map

The historic mining centers of Grass Valley and Nevada City dominate this detailed survey, showing a landscape where gold-rush era settlement patterns have evolved into a modern regional hub. The map provides excellent detail for genealogists, particularly through the mapping of the Old Saint Patrick's Catholic Cem and the newer Greenwood Memorial Cem. The intricate network of historic water systems, including the Lafayette Ditch and the Allison-Ranch Ditch, illustrates the enduring legacy of 19th-century hydraulic infrastructure in the foothills.

Industrial and institutional growth is evident at the Sierra College Nevada County Campus and the Nevada County Airport near Glenbrook. In the southern portion of the quadrangle, the transition from urban density to more open terrain is marked by smaller locales like La Barr Meadows and landmarks such as Wolf Mtn. This record preserves the precise location of legacy neighborhoods like Boston Ravine and Hills Flat alongside modern arterial routes such as the Nevada City Hwy.
