These photos were taken at Petroglyph National Monument on the West Mesa near Albuquerque New Mexico.
The following quote is from a pamphlet handed out at the visitor center.
” The West Mesa, a 17 mile long table of land west of the Rio Grande emerged about 200,000 years ago when lava flowed from a large crack in the Earth’s crust. Layer upon layer of lava flowed over and around the existing landforms. Eruptions continued from isolated points along the fissure, forming the cones as we see today. Over time, softer sediments on the mesa’s eastern edges eroded leaving a jagged edged escarpment strewn with basalt boulders that broke away from the lava caprock. This is the natural setting for petroglyphs as you see today.
Long ago people discovered that chipping away the rock’s thin desert varnish revealed a lighter gray beneath and left a lasting mark. American Indians believed these images were as old as time. Archaeologist estimate that most of the images were made 400 to 700 years ago by the ancestors of today’s Native people. Some images maybe 2,000 to 3,000 years old.”
I’ll have more photos soon.
All photos taken on an iPad mini.
