About this map

Rocklin serves as a central hub in this modern topographic landscape, where suburban expansion meets a complex network of historic water management features. The area's topography is defined by prominent rises like Boulder Ridge and Sugarloaf, while the southern reaches meet the northern shoreline of Folsom Lake at Dotons Point. The distribution of residential communities such as Granite Bay and Hidden Valley is closely tied to the traditional water routes of the Boardman Canal and Baughman Canal, highlighting how 19th-century infrastructure continues to shape modern land use.

Water control remains a dominant theme across the terrain, with the Caperton Canal and Antelope Canal snaking through the hills north of Penryn. For those researching local heritage, the Newcastle Cemetery provides a fixed point of historical reference near the northeastern corner. The map also traces the modern corridor of Interstate 80, which follows the general path of earlier transportation routes between the Sierra foothills and the valley floor.
