Presidential Proclamation -- Organ Mountains-Desert Peaks National Monument
- - - - - - -
BY THE PRESIDENT OF THE UNITED STATES OF AMERICA
In southern New Mexico, surrounding the city of Las Cruces in the Río Grande's fertile Mesilla Valley, five iconic mountain ranges rise above Chihuahuan Desert grasslands: the Robledo, Sierra de las Uvas, Doña Ana, Organ, and Potrillo Mountains. These mountain ranges and lowlands form the Organ Mountains-Desert Peaks area.
The Organ Mountains-Desert Peaks area is important for its ruggedly beautiful landscape and the significant scientific, historic, and prehistoric resources found there. The abundant resources testify to over 10,000 years of vibrant and diverse human history of many peoples. Objects left behind by this multi-layered history and spread throughout this geologically and ecologically diverse landscape enhance the experience of visitors to the area and represent a vital resource for paleontologists, archaeologists, geologists, biologists, and historians.
Archaeologically rich, the Organ Mountains-Desert Peaks area features hundreds of artifacts, rock art, dwellings, and other evidence of the Native peoples of the area. Three of the many rock art areas are in the Las Valles Canyon in the Sierra de las Uvas, the Providence Cone area in the Potrillo Mountains, and the Doña Ana Mountains. Scattered Paleo Indian artifacts, including those from the Folsom and Clovis cultures, represent the first people who lived in southern New Mexico and have been found in the Robledo and Potrillo Mountains as well as the Las Uvas Valley. The majority of the cultural items known to be in the Organ Mountains-Desert Peaks area are from the Chihuahuan Archaic period between 8,000 and 2,000 years ago. Diverse rock art images, along with ceramic fragments, demonstrate that the area was the scene of many cross-cultural interactions as the region's early occupants transitioned over time from roaming hunters to semi-permanent villagers.
The deeply creviced peaks of the Organ Mountains, named in 1682 by early European explorers for their resemblance to organ pipes, conceal numerous ancient dwellings, including La Cueva, and other caves where smoke-blackened ceilings evidence long-extinguished campfires. The Native people of these mountains used natural overhangs for shelter and food storage, and their obsidian points, basket fragments, and food remains are still present. Small caves and pit-house villages can be found across the landscape, including ruins of a ten-room pueblo in the Robledo Mountains. 2
El Camino Real de Tierra Adentro National Historic Trail memorializes an early trading route linking numerous pre-existing Native American footpaths to connect Spanish colonial capitals. The Trail, used through the 19th century by travelers, traders, settlers, soldiers, clergy, and merchants, skirts the Organ Mountains-Desert Peaks area as it follows the Río Grande Valley. Explorers and travelers along the Trail documented the marvels of this area in their journals and explored the mountains in search of mineral riches and game. Historians continue to study the southernmost portion of the area, which was acquired in 1854 as part of the Gadsden Purchase, the final territorial acquisition within the contiguous United States.
In the 1800s, the Organ Mountains-Desert Peaks area was central to several battles among the Apaches, Spanish, Mexicans, and Americans, and between Union and Confederate troops. The first Civil War engagements in New Mexico were fought in the Organ Mountains when Confederate soldiers used Baylor Pass Trail to outflank Union soldiers. In a Robledo Mountains legend, the famed Apache leader Geronimo is said to have entered a cave to avoid U.S. soldiers; while the soldiers stood guard at the only entrance of what is now known as "Geronimo's Cave," the Apache leader mysteriously disappeared without a trace. An 1880s U.S. military heliograph station, the remains of which still stand at Lookout Peak in the Robledo Mountains, transmitted Morse code messages during the Army's western campaigns.
In the late 1850s, John Butterfield developed the Butterfield Overland Trail, a mail and passenger stagecoach service from Memphis and St. Louis to San Francisco. Butterfield set upon improving the segments of the Trail in southern New Mexico that had been previously used by Spanish explorers, the Mormon Battalion, and western settlers. Crossing the Organ Mountain-Desert Peaks area are about 20 miles of the Trail, along which sit the remains of at least one stage stop.
Visitors to the Organ Mountains can still see remnants of Dripping Springs, a once-popular resort and concert hall, built in the 1870s and converted into a sanatorium before its abandonment and decay. In the late 19th century, the infamous outlaw Billy the Kid (William H. Bonney) repeatedly traversed this area. While hiding in the Robledo Mountains, "the Kid" inscribed his signature, which is still visible today, on what is now known as "Outlaw Rock." During World War II, the Army Corps of Engineers constructed 18-acre bombing targets, the remains of which still dot the landscape.
The long, diverse, and storied history of this landscape is not surprising given its striking geologic features and the ecological diversity that they harbor. The dramatic and disparate mountain ranges of the Organ Mountains-Desert Peaks area tower above the surrounding grasslands and deserts of the Río Grande watershed, while the Río Grande winds through the valley between the ranges. From the sedimentary deposits of the Robledo Mountains in the west, where the story of ancient life and activity is recorded in fossilized footprints, to the needle-like spires of the Organ Mountains in the east and the ancient volcanic fields and lava flows in the south, these peaks trace the region's varied geologic history. 3
The Sierra de las Uvas, the westernmost of the peaks, are low volcanic mountains that bear the red tint of the lava from which they formed over 10 million years ago. The tallest, Magdalena Peak, is a lava dome rising 6,509 feet above sea level. For millennia, the ridges, cliffs, and canyons of the rugged Sierra de las Uvas have defined the movement and migration patterns of humans and wildlife alike. The Robledo Mountains, which are composed of alluvial limestone bedrock and contain numerous caves, have long been an important site for research on the formation of desert soils and sedimentary rock, including geological studies of sedimentation and stratigraphy.
The Potrillo Mountains and volcanic field are testament to the area's violent geologic history of seismicity and volcanism. Millions of years after the Cenozoic tectonics that opened the Río Grande Rift, volcanic activity left its mark on the surface, which is punctuated by cinder cone and shield volcanoes, thick layers of basalt, craters, and lava flows. The Potrillo volcanic field contains over 100 cinder cones, ranging in age from 20,000 to one million years old. The Aden Lava Flow area is characterized by lava tubes, steep-walled depressions, and pressure ridges that memorialize the flow of lava that created this unique landscape.
The volcanic field also contains five maars, or low-relief volcanic craters. Kilbourne Hole, a maar with unique volcanic features that the Secretary of the Interior designated as a National Natural Landmark in 1975, is over a mile wide and over 300 feet deep. The sparkling yellow and green olivine glass granules found inside rocks blown from the crater attract amateur and professional geologists to this site, and its resemblance to the lunar landscape provides scientists and visitors with other-worldly experiences, as it did for the Apollo astronauts who trained there. A slightly smaller maar, Hunt's Hole, brings visitors and geologists to the southeastern corner of the Potrillo Mountains complex. The wide range of unique and exemplary volcanic features in the Potrillos makes this area a center for research in geology and volcanology.
The iconic Doña Ana Mountains include limestone ridges, hogbacks, and cuestas topped by monzonite peaks, including Summerford Mountain and Doña Ana Peak, the highest of these at nearly 6,000 feet. To the east, the steep, needle-like spires of the Organ Mountains rise to over 9,000 feet and have been a landmark for travelers for centuries. These block-faulted, uplifted mountains expose geologically significant Precambrian granite and metamorphic basement rocks.
Much of the area is ripe for paleontological discovery. For example, Shelter Cave in the Organ Mountains is a well-documented fossil site, including fossil remnants of ancient ground sloths, birds, and voles. The Robledo Mountains are also an important site for paleontological research; the fossilized tracks and remains of prehistoric creatures preserved there play a vital role in our understanding of the Permian period. This area, along with the Organ Mountains, also contains abundant invertebrate fossils. The congressionally designated Prehistoric Trackways National Monument is adjacent to, and shares its paleontologically rich geologic formations with, the Organ Mountains-Desert Peaks area, suggesting that this landscape could yield many more significant fossil discoveries. Among the volcanic cones in the Potrillo Mountains is Aden Crater, a small shield cone where a lava tube housed 4
the 11,000-year old skeleton of a ground sloth, one of few ever recovered with skin and hair preserved and a key to understanding the extinction of this and other species.
The diverse geology underlies an equally wide array of vegetative communities and ecosystems, which range from low-elevation Chihuahuan grasslands and scrublands to higher elevation stands of ponderosa pine. Seasonal springs and streams in the mountains and canyon bottoms create rare desert riparian ecosystems. These communities provide habitat for many endemic and special status plant and animal species.
Throughout the area, the characteristic plants of the Chihuahuan desert are evident. Tobosa grasslands can be found in the desert flats, punctuated by creosote bush and mesquite, as well as sacahuista, lechuguilla, and ferns. In the Sierra de las Uvas Mountains, black grama grasslands appear on the mesas while juniper woodlands and Chihuahuan vegetation give way to higher elevation montane communities. Formed by a series of alluvial fans, bajadas extend out from the base of the area's mountains and provide purchase for oak species, Mexican buckeye, prickly pears, white fir, willow, catsclaw mimosa, sotol, agave, ocotillo, flowering cactus, barrel cactus, brickellbush, and tarbush. The Potrillo Mountains are home to desert shrub communities that also include soaptree yucca and four winged saltbush.
These species are emblematic of the Chihuahuan Desert, and the diversity of plant and animal communities found here is stunning. The transitions among vegetation zones found in the Sierra de las Uvas and Potrillos make this area an important resource for ecological research. Similarly, the Doña Ana Mountains abut one of the Nation's long-term ecological research areas, making them an important feature of many studies in wildlife biology, botany, and ecology.
The Organ Mountains are home to alligator juniper, gray oak, and mountain mahogany, as well as the endemic Organ Mountain evening primrose, Organ Mountains giant hyssop, Organ Mountains paintbrush, Organ Mountains pincushion cactus, Organ Mountain figwort, Organ Mountains scaleseed, night-blooming cereus, Plank's Catchfly, and nodding cliff daisy, and likely the endangered Sneed's pincushion cactus.
The area also supports diverse wildlife. Across the Organ Mountains-Desert Peaks landscape, many large mammal species can be found, such as mountain lions, coyotes, and mule deer. The Organ Mountains were also historically home to desert bighorn sheep. Raptors such as the golden eagle, red-tailed hawk, and endangered Aplomado falcon soar above the area's grasslands and foothills, where they prey on a variety of mice, rock squirrels, and other rodents, including the Organ Mountains chipmunk.
The area's exceptional animal diversity also includes many migratory and grassland song birds and a stunning variety of reptiles, such as black-tailed, western diamondback, and banded rock rattlesnakes; whipsnakes and bullsnakes; and tree, earless, Madrean alligator, and checkered whiptail lizards. Birds such as Gambel's quail, black-throated sparrow, ladder-backed woodpecker, verdin, black-tailed gnatcatcher, lesser nighthawk, Scott's oriole, and cactus wren also make their homes here, along with many species of bats. Other mammals, including black-tailed jackrabbits, cactus mice, and kangaroo rats, 5
inhabit the area. One of several species of rare terrestrial snails in the area, the Organ Mountain talussnail, is also endemic.
The protection of the Organ Mountains-Desert Peaks area will preserve its cultural, prehistoric, and historic legacy and maintain its diverse array of natural and scientific resources, ensuring that the prehistoric, historic, and scientific values of this area remain for the benefit of all Americans.
