The Missouri River carves a winding path through the northern plains of Chouteau County, creating distinctive geographic markers like Evans Bend and Shonkin Bar. This ranching landscape is defined by the drainage systems of Shonkin Creek and several deep coulees, including O'Hanlon Coulee and Boyle Coulee. The map provides a detailed look at the rural landholdings of the early 21st century, identifying specific family operations such as the Streit Ranch, Freiling Ranch, and the O'Hara Brothers Ranch.
