Petroglyph National Monument: FAQs & Trip Guide

Most of the rock art etched in the escarpment is from 400 to 700 years old, although scientists say some of the images may be as old as 3,000 years, about the time people were migrating away from Chaco Canyon in northeast New Mexico and creating pueblos such as Acoma.

There are animal images: bighorn sheep, coyotes, bears, turtles, lizards, snakes, and birds, including macaws imported from Meso-America.

There are faces and elaborate masks, handprints, full-body images of people in feather headdresses holding corn plants, bows and arrows, and other implements, even kachinas (spiritual being in the Pueblo peoples religious beliefs, particularly the Hopi and Zuni tribes in the American Southwest).

Some are representative of religious or spiritual entities, and some tell stories of who came to the area and where they went.

Many of the glyphs are geometric: circles, spirals, squares, and other abstract designs. But they are not just rock art or graffiti. Think of petroglyphs as the street art of the past.

The context of each image is important and integral to its meaning, oriented to surrounding images and the landscape in which it sits. The placement was not casual nor random, although weathering has undoubtedly tumbled boulders down the escarpment, introducing a randomness.

Petroglyphs are powerful, cultural symbols reflecting the complex societies and religions of Indigenous people who lived here long before the Spanish arrived.

Native Americans, as the primary creators of these rock art, played a significant role in the cultural and historical narrative of the region, with their designs and symbols carrying deep spiritual significance for both their descendants and contemporary Native Americans.

As you walk the trail, it’s common to ask who made these pictures and why. There is any number of interpretations, but the National Park Service, which manages the national monument with the City of Albuquerque, notes the meaning of each petroglyph is known only to its creator.

Some experts think animal images represent rituals to assure a successful hunt.

Images involving plants may be part of ceremonies asking for a bountiful harvest. Some represent wind, water, rain, and lightning, while others made by holy people or medicine men might be calling upon spirits and gods to bring healing or protection or represent spiritual emergence or journeys.

Others might have been carved as part of rite of passage ceremonies. There are even some crosses more recently carved by Spanish settlers, adding to the layers of heritage at the site.

The original artists are, of course, long gone, although descendants who are today’s Pueblo people may indeed know the meanings. But many of the images have supernatural, spiritual significance and are considered sacred by Pueblo people.

The site of the national monument has a history almost as interesting as the petroglyphs themselves. The geologic history of Albuquerque’s West Mesa, including the formation of this volcanic basalt escarpment, plays a crucial role in the significance of the monument. More than 200,000 years ago, five volcanic eruptions occurred west of the Rio Grande fault, through which the river now flows.

The resulting lava erupting from the ground here is much older than the lava that makes up El Malpais farther west. Travel Interstate-25 just north of Los Lunas, at the Isleta Pueblo village, and you’ll pass through the layer of lava defining the escarpment.

On high ground east of Albuquerque, look west, and you’ll see the cones resulting from the fissure. The dormant (not extinct) volcanoes are named Butte, Bond, Vulcan, Black, and JA, after the initials painted on its side by students from John Adams Middle School.

Lava flowed from the fissure to a depth of up to 50 feet. The lava contains high concentrations of iron, manganese, and calcium, which combine to give the rock its gray color.

Rain, wind, and variable temperatures eroded underlying and overlying sediments, exposing the basalt layer. Then, over time, minerals in rock surfaces oxidized, creating the glossy, almost-black desert varnish.

Long ago, native people as well as Spanish settlers discovered that images could be created on the faces of the boulders by chipping away at this dark layer to expose the lighter rock below.

This area, part of the Rio Grande Valley, not only showcases the geological history but also protects numerous archeological sites, highlighting history and the significant role of the Rio Grande in shaping the landscape.

Petroglyph National Monument is in Albuquerque, New Mexico, on Western Trail NW, off of Unser Boulevard.

The Petroglyph National Monument headquarters and visitor center are off Unser Boulevard at Western Trail. Take I-40 to Unser Boulevard, head north, and follow the signs about three miles before turning on Unser.

Access to the monument is free, but Boca Negra Canyon charges a $1 parking fee on weekdays and $2 on weekends.

In some areas, yes. Dogs must be kept on a leash six feet or shorter. They are allowed on the trails at Piedras Marcadas Canyon and only in the petroglyph or middle section of Rinconada Canyon. Dogs are not allowed at Boca Negra Canyon. Service dogs are welcome throughout Petroglyph National Monument, providing they are properly identified and on a leash or halter at all times.

Tips for bringing dogs to Petroglyph National Monument:

• Bring dog booties to protect your pet’s paws from hot asphalt and sandy surfaces.
• Don’t forget to bring water for your dog.
• Clean up after your dog.
• Prevent dogs from chasing wildlife or dig holes.
• Keep dogs outside public buildings such as the visitor center, government offices, and public restrooms.

Check out Albuquerque’s dog parks.

No, Petroglyph National Monument is a day-use park free to the public.

Boca Negra Canyon, which is operated by the City of Albuquerque, is about a mile north of the visitor center. It has three paved trails for viewing up to 100 petroglyphs on self-guided tours. It has restrooms and water, shaded seating areas, and picnic tables. The parking fee is $1 on weekdays and $2 on weekends. Open 8:30 a.m. to 4:30 p.m. daily.

Seven miles north of the visitor center is Piedras Marcadas Canyon. Open from sunrise to sunset daily, it has an undeveloped 1.5-mile trail with some of the largest concentrations of petroglyphs in the monument. Water, restrooms, and other amenities are unavailable at this site.

The visitor center has restroom facilities, water, and a gift shop (open from 9 a.m. until 4 p.m.). The visitor center is open from 8 a.m. to 4:30 p.m. daily except for New Year’s Day, Thanksgiving, and Christmas.

You can pick up a brochure with maps of the three petroglyph sites but note that no petroglyph trails start at the visitor center.

You don’t have to go to the visitor center to hike the trails, however. Volcanoes Day Use Area, the mile-long Rinconada Canyon trail, and the slightly longer Piedras Marcadas Canyons trail can be hiked from sunrise to sunset by simply parking outside of the gated parking lots.

Stay on the trails. Petroglyphs may be cut into the rock, but they are fragile.
Watch out for sudden storms. Lightning in the open is dangerous.
Look for rattlesnakes. It’s their home. Report sightings to rangers.
Be protected. Wear protective shoes, sunscreen, and a hat.
Stay hydrated. Carry plenty of water. You may be near the city, but it’s still the desert.
