About this map

The Fox River carves through this LaSalle County landscape, anchoring the settlement of Sheridan and serving as a focal point for local industry. Large-scale extractive operations including several Quarries and numerous Gravel Pits line the riverbanks and the course of Somonauk Creek, which flows south into the Fox through a series of dramatic bends. To the north, Holiday Lake and the residential area of Northville illustrate the mid-century development of the region, while the Illinois Industrial School For Boys stands as a significant institutional landmark south of the main town.

Historical boundaries and transportation routes remain visible on this 1971 survey, most notably the Old Indian Treaty Boundary cutting diagonally across the center. Genealogists will find a high density of burial sites including St Johns Cem, Elerding Cem, and Lette Cem. The presence of the Burlington Northern line and an Old Railroad Grade near Catharine further documents the evolving rail infrastructure of the northern Illinois prairie.
