The Harvest Moon, the Equinox, and the Aldridge Petroglyphs come very close to meeting here. Two will dance together before our eyes at high noon. Leave behind as much of the 21st century as you dare. Walk to the Aldridge Petroglyphs, a gem among the jewels of BLM’s El Malpais National Conservation Area, on Sunday, September 22nd, 2013.

Come for the poetry of light and shadow. Observe the high noon sun shadow creep over a petroglyph calendar. Deeper reflection invites reverence for the wisdom of the ancestors, understanding of the forces of nature, and pondering humanity's next step.

Full moon will be on September 19 at 7:13 AM and below the horizon during our visit. Autumnal Equinox will be after our walk on September 22 at 2:44 PM. Please get in touch if you wish to do citizen science by coming early and/or staying late to record other sun/moon/planet rise/set phenomena.

Appreciate the artistry of the ancestors. These 2 panels have many rich images. Although precise dating of rock art is difficult, we will unfold the history during its creation and relate it to other familiar sites, like Chaco, Bandelier, Mesa Verde, Cahokia, Phoenix, & Mexico City.

Visit with respect. We will refrain from touching, or climbing on or atop ancestral sites. We will approach gracefully and refrain from eating or drinking around these panels. Please enjoy: http://www.youtube.com/watch?v=AvAuUeJoTIQ

Bask in the sun on a Cretaceous shore with little worries for the sharks whose teeth we will observe. Ponder the periodic inundation of the continents during times of global heating. Connect these underwater sediments on which we will tread with the CO2 we release driving to & fro. Be a responsible CO2 emitter and carpool if you can.

TIMING Depart at 10:00 AM sharp from the Ranger Station and caravan in your vehicles entirely on paved road to the trail head. Arrive at the parking area at 10:30 AM. Walk 1.25 miles with a gentle 100 foot elevation change in Federal Wilderness off-trail over easy terrain. Arrive at the petroglyph panels by noonish for lunch. Return by 2 PM to the vehicles.

This hike is entirely off trail over gentle terrain. This hike is not recommended for people under 12 years old, or for those not used to hiking at 7200 feet. PLEASE CONTACT A BLM-ER IF YOU CHOOSE TO LEAVE THE GROUP.

LOCATION The BLM ranger station is located 9 miles south of I-40 exit 89 near Grants, NM on State Road 117 at approximately mile 47.5. It’s gates are open daily from 8:30 AM to 4:30 PM. Map:

GEAR Wear sturdy footwear & long pants, or have cat balance to avoid the pokey cactus and jagged rocks. Bring a lunch or snack and plenty of water. Watch the forecast and be prepared for sun and rain.
