About this map

Spring Valley and the winding course of the Jacks Fork River define this Ozark landscape, where the karst topography of Shannon County is on full display through numerous subterranean features. High bluffs and deep hollows like Stillhouse Hollow and Leatherwood Hollow surround the river corridor, which was integrated into the Ozark National Scenic Riverways by the time of this survey. The map identifies several notable caverns, including the prominent Jam Up Cave, Peter Renfro Cave, and Sycamore Cave.

Upland areas such as Montier and the township of Birch Tree show a scattered network of rural homesteads and family burial grounds. Researchers can find several local cemeteries including Dyer Cem, Turkey Oak Cem, and Duncan Cem, often located near crossroads or along ridges like Jenny Ridge. The mapping also captures local water sources like Rymer Spring and Bunker Hill Spring, which were vital for early settlement and agriculture in this Missouri timber and river country.
