The Carrizozo lava flow is 5,000 years old and 75 km from event to tip. He also added that the Carrizozo Malpais and the McCarty’s lava flow in Cibola County are the youngest, longest, lava flows on the North American continent. “They were really bad because they put out gasses.” Carrizozo Land Partnership: The Carrizozo Land Partnership (CLP) provides access to recreators wishing to enter public lands managed by the BLM, between the Carrizozo Lava Flow and the White Sands Missile Range which can only be reached by crossing private land. This part of the long Tularosa Valley contains many square miles of buckled, twisted basalt lava, part of an extensive flow up to 165 feet thick and over 45 miles long that originated from several nearby volcanoes, including one vent now known as Little Black Peak, 9 miles northwest of the dusty, windswept town of Carrizozo. “These have environmental consequences that just aren’t really appreciated because they’re not big, bad, and explosive,” Dr. The 3/4 mile Malpais Nature Trail offers a close-up look of the lava surface. He pointed out that the flows had a tremendous impact on the landscape as they flowed away from the eruptions. Allen (1952) estimated, based on visual observation, that the flows are less than 1000 years old, and Weber (1964) estimated the age as 1500 yrs old. No carbon suitable for C-14 analysis has been found under the Carrizozo flows.

“It’s very complicated and we’re just learning how to map those that sequence,” Dr. The apparently-young Carrizozo lava flows have proven very difficult to date. Crumpler indicated it’s actually a combination of many tiny, different lava flows. Though from space the Carrizozo Malpais might appear to be one big flow, Dr. Crumpler told KRQE there is evidence the slow-moving Carrizozo eruption lasted for several years. The Carrizozo lava flow is 75 km from event to tip, researchers estimate. The texture, shown in the picture below, has the appearance of a coiled rope. One of the most apparent is the pahoehoe (pah-hoy-hoy) texture of the surface of the flow.

“Estimates of the volume of the lava that was actually erupted is around five cubic kilometers, plus or minus it’s very imprecise.” The Carrizozo Malpais preserve many features that are observed in currently-forming Hawaiian-style lava flows. Larry Crumpler, Research Curator at the New Mexico Museum of Natural History and Science told KRQE the lava flow started from an unusual volcanic eruption that was very large in volume, as evidenced by the photos. NASA’s International Space Station recorded photographs of an ancient lava flow stretching across the desert on the west side of Carrizozo.Ī member of the space station took a photo of the Carrizozo Malpais, a huge basaltic lava flow believed to be about 5,000 years old.ĭr.
