An important paper is receiving high media visibility this month, for good reason. It is titled: Dating North America's oldest petroglyphs, Winnemucca Lake subbasin, Nevada. The paper by LV Benson, et al., appears in the Journal of Archaeological Science, Volume 40, Issue 12, (December 2013). Highlights, from the Journal's website:
-Petroglyphs in the Winnemucca Lake subbasin, Nevada, were carved prior to 10.5 cal ka.
-A deep lake in the Pyramid and Winnemucca Lake subbasins persisted until ∼9.3 cal ka.
-The designs of the Winnemucca Lake glyphs are similar to those found at Long Lake, Oregon.

They devoted thoughtful consideration to “The Question of Age” and included excellent photographs.
