Illinois Classic USGS Quads

The 1:24,000 scale, 7.5 minute maps are the standard for topographic mapping in the US. Many outdoors people still prefer the classic quads due to the unmatched level of detail, accuracy, and symbology honed over a 100-year period by dedicated cartographers and surveyors employed by the US Government.
