Moon Lake and the surrounding Sandhills wetlands define this portion of Brown County, where a dense network of lakes and marshes punctuates the landscape. The Calamus River and its S Fork Calamus River wind through the eastern terrain, anchoring a hydrographic system that includes named features like Philbrick Lake, Crystal Lake, and Enders Lake. This 2017 survey reflects the remote, ranching-oriented character of the region, where infrastructure is limited to few access points such as Moon Lake Rd and Hill Rd.
