Teter Rock is 12 miles east of Cassoday in Greenwood County, Kansas. In the 1950s, James Murle Teter persuaded an oil pipeline crew to drag this limestone monolith a couple of miles and erect it on a ridge that divides the Cottonwood, Verdigris, and Walnut watersheds. There's a fascinating Teter Rock chapter in Jim Hoy's book, Flint Hills Cowboys. East of Cassoday in Greenwood County, Kansas. July 16, 2007.
