Looking towards Albuquerque’s West Mesa, one can’t help noticing the area’s distinctive geology and topography. A closer look reveals many clues of an active cultural and geologic history.
Understanding the volcanic landscape
Roughly 30 million years ago, the earth’s crust began stretching apart in an east-west direction. This action caused the Sandia Mountains to rise above the sinking basin now called the Rio Grande Rift Valley. The slow movement set off chain reactions that resulted in the Albuquerque volcanoes much later. Between 155,000 and 200,000 years ago, a crack formed in the earth’s surface allowing hot, liquid magma to shoot up and ooze eastward across the landscape at about 5-10 mph. These fissure eruptions occurred six times.
At the end of the last eruption, six cinder cones were formed due to a buildup of ash, cinder, and cooling lava rock. The result was a series of six volcanoes and a caprock of basalt, 17 miles long and 12 miles across. The heavy basalt eventually crumbled and fell apart, leaving the boulders that we see today.

Additional history
When the Spanish arrived in 1540 and began settling the area around 1600, ancestral Puebloan life changed dramatically. Under Spanish rule, the numerous Pueblos along the Rio Grande began to suffer from illness and disease. After extensive and secret communications with each other, the Pueblos successfully rose up against the Spanish in the Pueblo Revolt of 1680. In 1692, the Spanish returned. The area changed again. The sweeping grasslands across the volcanic mesa gave way to rudimentary cattle and sheep ranches. The reality of private land ownership became more and more prevalent with new land grants given to Spanish colonists by the King of Spain.

Protection of a sacred place
Over the next few hundred years, the Villa de Albuquerque grew into the modern city we know today. As urban development began expanding westward in the 1970s, the sacred lands of the petroglyphs became threatened. The desecration and destruction that this area faced inspired local citizens, Tribal elders, and scientists to advocate for the protection of these irreplaceable resources. Their hard work finally paid off on June 27, 1990, when Petroglyph National Monument was established by an act of Congress.
Five dormant volcanic cones and a seventeen-mile basalt escarpment show how a series of eruptions over 100,000 years ago formed the West Mesa. The basalt boulders that tumbled down to the escarpment’s edge later provided an ideal material for carving Puebloan and Spanish petroglyphs. Changing hands over the centuries, this land is now part of the Open Space network.
Petroglyph National Monument is unique not only in its history and landscape but in its management as well. This 7,244-acre monument relies on a partnership between the National Park Service (NPS) and the City of Albuquerque Open Space Division to protect its nearly 20,000 petroglyphs and provide recreational and educational opportunities to the public.
Petroglyph National Monument protects one of the largest petroglyph sites in North America featuring designs and symbols carved onto volcanic rocks by Native Americans and Spanish settlers 400 to 700 years ago. These images are a valuable record of cultural expression and hold profound spiritual significance for contemporary Native Americans and for the descendants of the early Spanish settlers.
Petroglyph National Monument has much more to offer than the cultural resources for which it is so well known. Various types of wildlife utilize this narrow corridor, some in transit during migration, others for their entire lifespan. Plants, birds, insects, and animals, all are part of the ecosystem that Petroglyph National Monument holds in this tiny strip of land.
Another less popular but well-known resident of the monument is the rattlesnake. This landscape is home to several species; please be careful when you are visiting the national monument.
While hiking, you will notice a wide range of native desert plants.

Visitor Center
Petroglyph National Monument is located about 7 miles northwest of downtown Albuquerque. Although I suggest that all visitors make their first stop at the visitor center, it is important to know that there are not any petroglyph viewing trails at the visitor center. (If you are being dropped off at the visitor center, please ask the driver to wait for you since you will need to be driven to the actual petroglyph viewing trail system of your choice.)
The visitor center is located at the intersection of Unser Blvd. NW at Western Trail. The petroglyph viewing trails are a 1- to 6-mile drive from the visitor center.
While at the visitor center, park staff will inform you of your trail options based on your timeframe and the degree of difficulty of the trail then provide you with driving directions to the trail of your choice. Be sure to get your official park brochure and trail maps while there.
Time spent in the park varies from a minimum of 30 minutes to over 4 hours though the average visit is 1-2 hours.
There is no public transportation to the monument so you’ll need to drive or take a cab or ride-share to reach it. The park welcomes visitors daily. The information center is open 8:30 a.m. to 4:30 p.m.

Viewing the petroglyphs
These remnants of erupting volcanoes which produced the basalt that became the canvas for people for thousands of years stand starkly against the western horizon. A moderate hike will take you partway up some of these volcanic cones. Be sure to stay on the trails. It takes decades for this fragile volcanic landscape to recover from a single footstep.
All of the petroglyph viewing trails are outdoors so be prepared for the day’s weather and dress accordingly. Take plenty of water and wear sturdy shoes that provide ankle support or hiking boots since the trails are along the natural surface which is oftentimes uneven ground. A wide-brimmed hat is advisable in summer as there is no shade.
Remember to lock your vehicle, secure your valuables, and set your vehicle’s alarm system. Do not invite a thief by leaving valuable items visible inside your car.
Petroglyph National Monument is comprised of four different trails with the visitor center somewhat centralized between the trailheads.
Three trails allow for petroglyph viewing and one trail does not. These trails range in length from one to four miles roundtrip and in degree of difficulty from easy to moderately strenuous. Trail guides for each trail system are available at the visitor center.

Boca Negra Canyon
Boca Negra Canyon has the most developed trail in the Petroglyph National Monument

- Details: Located on the western edge of the monument, this trail system offers scenic miles of hiking around the volcanic cinder cones. Although the area is void of petroglyphs, you’ll enjoy the clear views of the Rio Grande valley and the Sandia Mountains from the scenic overlook. Trails vary in length from 1 mile to 4 miles round-trip.
Volcanoes Trail is about 3.5 miles round trip loop and is considered easy to moderate. The entire trail starts at the parking lot and goes past the JA Volcano to the scenic overlook, up to the Vulcan Volcano, and back to the parking lot with sweeping views of Albuquerque and the Rio Grande Valley throughout.
JA Volcano and the Albuquerque Overlook is an easy 1 mile round trip from parking lot to scenic overlook and back. This sub-section of the trail departs from the parking lot and heads east to a scenic view of the Rio Grande Valley, Albuquerque, and the Sandia Mountains. You will have to turn around the way you came back to the parking lot to complete it. This trail has two shaded rest areas with benches.
Vulcan Volcano Loop is a moderate 2 miles around Vulcan Volcano and back. This sub-section of the the trail can be found by going to the northside of the main parking lot near the gate.
The trail along the eastern base of Vulcan can be difficult to find. A gradual incline up the east side of Vulcan leads to a level, mini-volcanic valley. Continue on trail and go left (south) when you approach the ‘Y’ on the northwest side of Vulcan. At next ‘Y’ go left again for an up-close look at this well preserved cinder cone. Follow trail down, continuing south on old road which leads back to the parking lot.
North Volcanoes Loop Trail is a moderate 2.3 miles. This section of the trail connects to the Vulcan Volcano Loop and will take you to the remnants of a historic corral.
Worth Pondering…
Each of these rocks is alive, keeper of a message left by the ancestors…There are spirits, guardians; there is medicine…
