HistoryA character grade: shown, never part of Shell Knob’s overall grade.
Missouri towns list about as much on the Register as the country (a typical Missouri town has 2.4 per 10,000 residents, the U.S. 2.4), so Shell Knob’s 0.0 sits below most of its state (23% of Missouri towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D− to C−. The pre-1940 share (±0.8 points) is firm at this size. The founding year is the first post office, not a stated founding date.

What stands out about Shell Knob’s past

Located in the Ozark Mountains, Shell Knob was established in 1835 on the banks of the White River when Henry and Elizabeth Yoachum Schell built a trading post. The "c" was left off the name when the post office was established in 1872. The Schells left in 1846 and went on to establish the community of Jacket, Missouri. In 1959, Table Rock Dam was completed and Table Rock Lake filled.
