Last Chance Bench and Canavan Bench dominate this high-plains landscape in Chouteau County, where the topography is defined by the sharp relief of the breaks and coulees draining toward the river valley. The map reveals a sparse but deliberate network of country roads, including Duvall Rd and Happy Hollow Rd, which navigate the elevation changes between the level benches and the lower drainages. A notable crossing point occurs at Flat Creek Pass, providing a transition through the broken terrain near the headwaters of Flat Cr. To the northeast, the land drops away toward the water, where Wolf Island sits as a prominent landmark. This 2020 survey illustrates how the land has been partitioned and accessed, with features like Liberty Spring and various named routes such as Hopkins Hill Rd and Hawarden Rd serving as critical reference points for local land management and navigation.
