Radiocarbon dating rock art
Rock Art can be “interpreted” in many ways, including by modern artists and spiritual practitioners with purposes which may have either a lot or very little to do with the reasons it was produced long ago.
These modern interpretations can be useful to those who engage in them, even giving great pleasure and serenity.
The overflowing lake left telltale crusts of carbonate on these rocks, according to study researcher Larry Benson of the University of Colorado Boulder.
The true age of this rock art had not been known, but a new analysis suggests these petroglyphs are the oldest North America, dating back to between 10,500 and 14,800 years ago.
When we can both assign a date to rock art and identify the present-day descendants of those who made it, we know where their ancestors were at some time in the past.
Then we may have something like the oldest histories in the world.
Renfrew (1973) called it 'the radiocarbon revolution' in describing its impact upon the human sciences.
Oakley (1979) suggested its development meant an almost complete re-writing of the evolution and cultural emergence of the human species.
