Two rectangular blocks with inscriptions originally on three sides of each were first reported in 1907 by the Cornell Expedition to be built into the wall of a guardhouse on Develi-Kayseri road, at the skirts of Mt. Erciyes. Heavily damaged inscriptions cannot be read. On Tekirderbent 1 "divine Mount Harhari" (Hittite name of Mount Erciyes) is mentioned twice (see Hisarcık). Blocks are currently in Kayseri Museum. They are estimated to be from the 8th century BCE.
