Masonville serves as the central hub of this agricultural landscape along the border of Buchanan and Delaware counties. The town is defined by a rigid grid of streets, including Bernhart St and 215th St, while the surrounding countryside is partitioned into the expansive townships of t89n r7w, t89n r6w, t88n r7w, and t88n r6w. The local topography is carved by a network of waterways, most notably the meandering Coffins Creek to the north and Sand Cr to the east.
