2018 Map of Boulder

About this map

The waters of Carlyle Lake dominate the northwestern landscape of this Illinois quadrangle, where the Kaskaskia River and its East Fork define the local drainage patterns. The settlement of Boulder sits at the intersection of Quick Rd and Co Hwy 3, serving as a central point for the surrounding agricultural community. This area is notably dense with small family and community burial grounds, which provide significant genealogical value for the region. These sites, including Pritchett Cem, Old Carter Cem, and Hawkins Cem, are scattered across the rural townships of t3n r1w and t4n r1w. The map also illustrates the confluence of several minor waterways such as Brewster Cr and Gibbs Cr, which weave between a grid of county roads like Wortman Rd and Brink Rd, reflecting the persistent rural structure of Clinton County and neighboring Fayette County.
