Trip to the Petroglyphs east of Yuma
Yuma, Arizona - Tuesday, December 21, 2010 by: Michael Townsend

We took a trip to the Petroglyphs east of Yuma. Very interesting!

My understanding is the site is like
Stonehenge but for the natives of Southern Arizona.

If we had a sunny day, we could have lined up some of the stones to reveal a marker indicating Winter Solstice. The marker I was standing beside (above) is the Summer Solstice Indicator.  As it was December 21 well.......... But alas, no sun.
