Bobs Knob is a summit in McDonald County, Missouri, rising 1,106 feet, or 337 meters. Although it is shown as a mountain, the available record identifies it simply as a summit. Its name preserves the memory of “Old Bob,” a pioneer citizen for whom the height was named. Beyond its elevation and the origin of its name, little else is recorded here, but the place reflects how small named heights in the region remained tied to early settlement and local tradition.
