Black Beaver (1806-1888) was a Delaware Scout, interpreter and trapper. His Indian name was Sucktum- mah-kway. He spent many years in the Rocky Mountains, and led many expeditions. In 1834 he accompanied the Dodge-Leavenworth Expedition and during the Mexican War he served in the U. S. Army as a captain of Indian volunteers. In 1849 he led Capt. Randolph B. Marcy and others westward to Santa Fe via the California Road. He later occupied Camp Arbuckle, and became chief of a settlement called Beaversville. In 1853 Lt. Amiel Weeks Whipple visited him there. He settled in the Leased District prior to the Civil War and built a home there. In 1861 once the war began, he led Col. William H. Emory's Federal troops from Fort Cobb to Kansas. Confederates destroyed Black Beaver's property in retaliation. He filed a claim in 1872.
