About this map

The Meramec River winds through the heart of this Crawford County landscape, where the karst topography of the Missouri Ozarks is on full display. The area's complex hydrology is defined by significant natural features such as Onondaga Spring and Cathedral Spring, alongside the confluence of Huzzah Creek and Courtois Creek as they join the Meramec. Within the southern portion of the map, the Mark Twain National Forest encompasses much of the terrain, protecting the slopes around Lea Hill and the unique landform known as The Narrows.

Settlement patterns are concentrated around historic locales like Scotia and Vilander. Local family history is preserved at the Harrison Cem and Hardy Cem, while the region's transport history is visible at river crossings like Hog Trough Bridge and Campbell Bridge. The map details a network of rural roads, including Possum Hollow Rd and Thickety Ford Rd, which navigate the deep valleys and hollows like Opossum Hollow.
