About this map

Boulder Ridge and the Southern Pacific railroad corridor anchor this landscape of Placer County, where the transition from agriculture to suburban expansion is clearly visible in the 1970s updates. The rail line serves as the historic spine for a series of settlements including Newcastle, Penryn, Loomis, and Rocklin, each showing the characteristic cluster of development around the tracks. Evidence of the region’s earlier industrial foundations is found in the scattered mining operations such as the Mary Len Mine, Sicily Mine, and Alabama Mine situated in the ravines east of the main transit corridor.

Water management and recreation dominate the southern and western portions of the sheet. The expansion of Roseville is captured in purple revision tint, while to the southeast, the shoreline of Folsom Lake within the Folsom Lake State Recreation Area defines the topography. Institutions like Sierra College and Mount St Joseph Seminary appear alongside growing residential communities like Hidden Valley, illustrating the post-war growth that reshaped this portion of the California foothills.
