Cornerstone Ceremony, Palo Duro Canyon State Park, May 12, 1934
Celebrants gather for the cornerstone ceremony at Palo Duro Canyon's lodge. Federal partners typically decried cornerstones, but at this site local and state interests won out. State Park's Board chairman, David E. Colp, holds a trowel and NPS inspector George L. Nason stands at Colp's left.
