  • Crews manage wildfire near Lost Woman Crater

    A small wildfire near Lost Woman Crater is being managed by crews from the National Park Service and the Bureau of Land Managment. Recent heavy rains will minimize fire growth, but travelers may experience smoke on NM 53 near the continental divide.

Lava Tubes and Caving

Lava tube caves, with their fascinating geology and hidden ice formations, await your careful exploration. With a free caving permit and the proper equipment, you can experience these magnificent underworlds. For more information, such as which caves are available for entry, permitting requirements, recommended equipment, maps to caves, etc., please download a copy of our caving brochure.

Cave Permits

Caving permits are available at the El Malpais Information Center or at the Northwest New Mexico Visitor Center. These permits are free, but visitors will need to speak with a ranger about previous caving experience and receive cave safety and conservation information. Cave permits are only valid for the months indicated and for entry into specific caves. A new permit is required if visitors go to caves outside the monument and then return to re-enter caves here at El Malpais.

How Lava Tubes Form

Lava tubes formation

Modified from Bruce Rodgers, USGS

Lava tubes can form in two ways: as shown above, and another way not illustrated here, when new lava pushes in underneath older layers of lava flows, "inflating" them from underneath. These inflated areas later drain and leave behind empty lava tubes, usually very wide and low in cross-section profile. Many of the caves in the monument formed this way.

The Lava Flows

Lava flows in the El Malpais area

A history of the lava flows in El Malpais National Monument and surrounding area.

The El Malpais lava flows are of different ages and origins. The youngest is the McCarty's Flow, which is roughly 3,000 years old and can be seen on the east side of the monument along Hwy 117. The flow creates a stunning landscape in the Lava Falls area and the Lava Falls Loop Trail offers visitors an up close look at many pahoehoe lava features. The oldest volcanic rocks in the area are hard to see - dust, soil, and plants have covered them. However, the cinder cones of the Chain of Craters are still impressive for their 0.6-0.7 million year age. Mount Taylor and associated lava flows, northeast of the monument near Grants, are even more ancient at 1.5 to 3.3 million years old.

Did You Know?

Rough aa lava can be found near Cerro Rendija

Two distinct kinds of lava can be found in the varied flows of El Malpais. Lava is known by names from the Hawaiian Islands. Aa lava is clumpy and forms numerous irregular chunks, while pahoehoe lava cools to form smooth surfaces often covered with ropy textures. More...
