NABSQNO 14S-550160-3636165. This unnamed triple pillar natural arch has eroded through a projecting wall of Winchell limestone. It is located on private property above Possum Kingdom Lake in Palo Pinto County, Texas. However, both sides of the arch can be viewed from the lake below. Thus, access is by boat from any of the several public marinas or launch ramps on the lake. The largest opening has a span of 15 feet and a height of 7 feet.
