2015 Map of Putnam

About this map

The community of Putnam and the intersection at Lone Tree Corners anchor this 2015 study of the Illinois River valley's western bluffs. The landscape is defined by the sharp transition between flat agricultural uplands and the deeply dissected ravines leading toward the massive Senachwine Lake. A modern suburban-style residential pattern is visible surrounding Lake Thunderbird, with streets like Catalina Dr and Barbados Dr winding through the wooded terrain near Saint Joseph Cem. This development contrasts with the traditional grid of rural routes such as 700 Ave N and Bradford Blacktop Rd. Local transit and aviation history are preserved through sites like the Ralph E. Daniels Airport and Edgar Read Airport, while family history is marked at Lone Tree Cem and Sugar Grove Cem along the quiet drainage of Crow Cr.
