The southeasternmost portion of Missouri, a distinct appendage known for its unusual shape, extends further south than the rest of the state. This geographical anomaly arose from historical events and surveying practices dating back to the early 19th century. The area’s existence is primarily attributed to the desire of a landowner to remain within the boundaries of Missouri during its establishment as a state.
The retention of this region provided the state with valuable access to the Mississippi River, enhancing its strategic importance for trade and transportation. Its inclusion also reflected the political influence and determination of particular individuals who sought to ensure the region remained part of the newly formed state, rather than becoming part of Arkansas, which was being organized simultaneously.
