James L. Murphy, "The 'Lost' Barnesville Track Rock," Ohio Archaeologist 59, no. 2 (Spring 2009): 29-34.
The so-called "lost" rock of the Barnesville Track Rock petroglyphs, Belmont Co., Ohio, is described and the first published photographs are provided. In some respects Whittlesey's 1872 drawing is more accurate than that provided in Swauger (1974). The carvings are exposed to weather and exhibit considerable degradation.
