Scott Sonner, of Associated Press, wrote an interesting short piece on Pyramid Lake, Nevada's petroglyphs which was published in the Columbus Dispatch.
"Ancient rock etchings along a dried-up lake bed in Nevada have been confirmed to be the oldest recorded petroglyphs in North America, dating back at least 10,000 years."-Scott Sonner
These are the same petroglyphs mentioned
which we posted about September 4th.
