About this map

The settlement of Pleasant Grove anchors this topographic study along the flat agricultural borderlands of Placer and Sutter counties. Surveyed in cooperation with State of California officials including Governor J. N. Gillett, the landscape is defined by a series of southwest-flowing waterways, most notably Auburn Ravine, Pleasant Grove Creek, and Curry Creek. These drainage patterns reveal the subtle contours of the Central Valley before modern large-scale leveling and development altered the natural flow toward the Sacramento River basin.

Transportation infrastructure at the edge of the valley is captured in transition, featuring the Western Pacific and the Northern Electric R. R. cutting through the southwestern corner near Riego. For genealogists and local historians, the map identifies specific community focal points like Eagle School and Alpha School, which served the dispersed farming families of this era. The detailed boundary between Sutter and Placer counties is clearly delineated, showing how early property and political lines followed the township and range grid.
