The Base Line Survey, a significant historical landmark in Schuyler County, Illinois, holds a remarkable place in the nations past. Located on US Hwy 67, just north of the Illinois River between Beardstown and Rushville, it bears witness to an essential moment in American history - where the 4th principal meridian intersects its base line.

The story of this landmark traces back to 1858 when William P. Dole and his team embarked on surveying the road using blazed trees as reference points. This method of measuring land by metes and bounds was critical for establishing property lines in the region, setting the foundation for all subsequent land surveys in Illinois.

Its strategic location near Beardstown and Rushville is a testament to its historical significance. One can almost imagine the excitement of those early days when Doles team marked this monumental junction. Today, the Base Line Survey stands about 0.9 miles from the marker on the northeast corner of Beardstown, and approximately 6.3 miles away from another significant monument in Rushville.

For researchers interested in unravelling the historical backstory of the area, detailed topographic maps offer a treasure trove of information. They not only capture cities, landmarks, and geographical changes over time but also provide a window into understanding how this region has evolved since the establishment of the Base Line Survey.

Just as captivating as the Base Line Survey is its nearby neighbor - Schuy-Rush Lake. While the American Historical Landmark Project documents numerous historic sites across Illinois, this lake offers an interesting detour for visitors. With a 2020 survey yielding a fish measuring an impressive 26.4 inches and weighing 8 pounds, its clear that there are many stories waiting to be discovered in the waters of Schuy-Rush Lake.

This project aims to preserve the rich history of these areas for future generations by providing aerial photographs of cities, towns, villages, and farmsteads along with brief historical narratives. This comprehensive approach ensures that even as time marches forward, the legacy of the Base Line Survey and its surrounding landmarks remain firmly etched in our collective memory.

As we journey through this remarkable landscape, let us remember the pioneering spirit that brought people to the Illinois River valley, marked by the Base Line Survey. This site remains a symbol of progress, resilience, and the unwavering human drive for exploration and discovery - a testament to our enduring fascination with the world around us.
