Proclamation on the Establishment of the Chuckwalla National Monument

In southeastern California, where the Mojave and Colorado Deserts intersect, ancient trails weave through a land of canyon-carved mountain ranges bound together by radiating alluvial bajadas and dark tendrils of dry wash woodlands. Sharing a name with the wide-bodied lizard that is commonly found here and derived from the Cahuilla word "čáxwal," the Chuckwalla region is a place of wonder that lies within the traditional homelands of the Iviatim (Cahuilla), Nüwü (Chemehuevi), Pipa Aha Macav (Mojave), Kwatsáan (Quechan), Maara'yam and Marringayam (Serrano), and other Indigenous peoples. It is imbued with religious, spiritual, historic, and cultural significance for Tribal Nations that trace their origins to these lands. The area contains an abundance of artifacts attesting to its connection to diverse human communities over thousands of years. The region's mosaic of habitats is also home to a remarkable array of plant and animal species. The dramatic contortions of its mountain ranges embody a fundamental story about the shaping of our world that scientists are still learning to decipher. The cultural, geologic, and ecological resources on Federal lands in the Chuckwalla region will continue to inspire and fascinate people and provide a scientific research trove for generations to come.

The Chuckwalla region comprises five geographically discrete areas located between Joshua Tree National Park and the Palen/McCoy Wilderness to the north, California State Route 78 to the east, the Chocolate Mountain Aerial Gunnery Range to the south, and the western boundary of the Mecca Hills Wilderness to the west. Woven together by the physical threads of Indigenous trails that radiate outward connecting peoples and places throughout the Southwest, the region carries significant cultural and sacred meaning for many Tribal Nations. The southern area is a vast and intact expanse of austere, beautiful mountain ranges and desert valleys stretching from the Mecca Hills and Orocopia Mountains in the northwest, to the Mule and Palo Verde Mountains in the northeast, and to the mesquite-studded draws of the Milpitas Wash in the southeast. The other four areas, which lie in the transition zone between the Mojave and Colorado deserts, are located at the base of the Cottonwood, Eagle, Coxcomb, and Palen Mountains.

The imprints of generations of Indigenous peoples are found throughout the region in the trails, tools, habitation sites, and spectacular petroglyphs and pictographs they left behind. The Chuckwalla region has also been marked by the passage of people on the major prehistoric and historic travel corridors that connected the region to the Pacific coast and the interior southwest. While only a small fraction of the region has been formally inventoried, myriad cultural resources have been documented, and there are likely similar historic sites and objects yet to be discovered. A few sites are well-known and easily accessible to the public; many others are concealed in labyrinths of rugged canyons and have not yet been formally studied.

Trails within the area helped to link important resources and people across the Indigenous homelands of the Chuckwalla region. For centuries, they facilitated trade and cultural exchange between peoples throughout the Southwest. Weaving through canyons, the trails connected indispensable water and other resources throughout the area. They were, and are, essential to the people who trace their origins to these lands, and provide a sense of connection between generations and between the physical and spiritual worlds.

In some places, the footfalls of past generations have etched these trails into the region's surface, wearing a clear path into desert pavement. Ceramics and lithic scatter are also commonly found along trail routes within the Chuckwalla region. The endless shifting of sand and alluvium have likely obscured artifacts in some locations. A prehistoric travel route ran through the core of the northern area between the Eagle and Coxcomb Mountains, connecting the Pinto Basin, where some of California's oldest artifacts have been found, and the Chuckwalla Valley. The relatively narrow gap between the Eagle and Coxcomb Mountains traversed by the corridor also creates the conditions for flash floods; as a result, artifacts are likely to be found below the surface of the wash rather than on its surface.

At least two trails that traverse the Chuckwalla region are sacred to Tribal Nations and bind their members to the land and to generations past. These trails, of which physical traces remain, are both ancient and modern, tangible places and passages that Tribes and Indigenous peoples evoke and visit through songs and dreams. Two versions of the Salt Song Trail pass through the region, connecting it to Tribal communities and sacred sites throughout the Southwest physically and through songs describing corridors, viewsheds, and the related geography and resources. While the Salt Song Trail can be traveled by foot, traditional singers also travel this trail by voice through songs passed down across generations and that Tribes and Indigenous peoples believe assist the transport of the spirits of the recently deceased.

The Xam Kwatchan Trail, which parallels the Colorado River in the vicinity of the Mule and Palo Verde Mountains along the eastern edge of the southern area, is maintained by the Quechan people and recognized by many other Tribes of the Lower Colorado River. Portions of the Xam Kwatchan Trail are still visible and may be traveled physically as the trail weaves through the area and links together three sacred peaks of the Southwest: Avi Kwa Ame to the north of the Chuckwalla region near Lake Mead, Palo Verde Peak within the southern Chuckwalla region and overlooking the Colorado River, and Pilot Knob to the south of the Chuckwalla region near Yuma, Arizona. It is a belief of the Quechan people that they also travel this trail through dreams to transport the living and deceased, and to tie them to these lands and to their origin at Avi Kwa Ame. The Palo Verde and Mule Mountains encompass sites of particular significance along this trail. The eastern side of the Palo Verde Mountains is particularly dense with evidence of human habitation, including trails, camp spots, and ceremonial fire hearths.

The Chuckwalla region has no perennial streams or lakes, but hidden within the southern area's mountain ranges are springs and natural seasonal water catchments (often referred to as tanks). Knowledge of these water sources has allowed Indigenous people to survive within this arid environment for thousands of years. The locations surrounding these springs and tanks are replete with artifacts, including stone tools, ceramics, remnants of habitations, and a dazzling array of petroglyphs and pictographs. In some places, the patina of naturally created desert pavement has been scraped away to form circles and images known as geoglyphs.

In a wide canyon at the heart of the Chuckwalla Mountains lies Corn Springs, a well-known cultural site. Amid the mountain range's rugged peaks and dry washes, the oasis at Corn Springs, which supports a stand of more than 60 California fan palms, has long been a beacon to the area's human occupants. Corn Springs contains extensive petroglyphs encompassing a diverse array of elements and representing contributions by many people over thousands of years. These petroglyphs, which are listed on the National Register of Historic Places, are carved into flat planes on the golden rocks found near Corn Springs.

Jutting from the desert floor north of Corn Springs, in an area just south of the community of Desert Center, sits Alligator Rock. A salient ridge containing dikes of aplite, Alligator Rock was both a milestone on the major Indigenous travel and trade route that passed through Chuckwalla Valley and an important prehistoric source of lithic materials. Flakes and tools crafted from the area's distinctive speckled stone have been documented in sites throughout Chuckwalla Valley.

In the eastern area, northeast of Alligator Rock and Corn Springs and north of the Little Chuckwalla Mountain Wilderness, Ford Dry Lake is now a sparsely vegetated playa in the Chuckwalla Valley at the base of the Palen and McCoy Mountains. Dense cultural sites have been documented along the lake's ancient shorelines, attesting to its use by generations of Indigenous peoples. Artifacts uncovered here include a variety of stone tools, ceramics, and other evidence of Indigenous habitation sites.

While seemingly inhospitable to humans, the Chuckwalla region has provided sustenance and material resources to the Indigenous peoples who have inhabited and traversed it for generations. Many of the region's native plants were gathered for food, including mesquite and ironwood seeds, wild grasses, and cacti. Mesquite, which thrives in the dry washes of the southern area between the Chocolate and Palo Verde Mountains, was a particularly important source of sustenance. Large quantities of the beans were collected in the summer and stored for use throughout the year. In 1972, a large ceramic olla (an earthenware vessel) containing mesquite beans was discovered in a rock shelter in the canyon-striated Mecca Hills of the far western corner of the southern area.

By the mid-1800s, the Chuckwalla region had caught the attention of non-Indigenous Americans seeking wealth in the underbelly of its mountains. In the 1860s, the Mule Mountains - near the California-Arizona border - were the site of one of the first discoveries of gold in Riverside County. Two decades later, the largest gold rush in Riverside County's history occurred when gold and silver were discovered in the Chuckwalla Mountains. Relics of historic mines, including shafts, trenches, equipment, and remnants of buildings, are present throughout the region's mountain ranges. A mining shaft, conveyor, and loading dock associated with the Model Mine, which operated around the turn of the last century, are located in the western foothills of the Chuckwalla Mountains.

In 1862, as gold seekers spread throughout the region, a miner named William Bradshaw sought to develop a route to connect the Coachella Valley with expanding mines on the east side of the Colorado River. A Cahuilla leader and another Indigenous trail runner provided Bradshaw with a map of existing Indigenous routes linking springs and tanks along the southern edge of the Orocopia, Chuckwalla, and Little Chuckwalla Mountains. He used the knowledge shared with him of these existing Indigenous trails to identify what became known as the "Bradshaw Trail," an overland route that traverses the Chuckwalla Bench through the heart of the southern area. Some of the springs and tanks, which had long been used by Indigenous peoples, became stagecoach stations associated with the Bradshaw Trail. Intrepid visitors can still drive the unpaved Bradshaw Trail, which the Bureau of Land Management (BLM) designated as a National Backcountry Byway in 1992.

In 1942, shortly after the United States entered World War II, the Department of the Army established a presence in the Chuckwalla region, reminders of which can still be seen across the terrain. In March of 1942, Major General George Patton selected a large swath of desert in California and Nevada, including a substantial amount of land in the Chuckwalla Valley, for a Desert Training Center to prepare United States Army units for desert combat. By the end of World War II, over a million soldiers had been trained at the facility. Small unit training exercises were held in Chuckwalla Valley, which the Army believed provided the best approximation of terrain they might face in parts of North Africa. The scars of tank tracks across the southern area's desert pavement can still be seen today, along with berms, trenches, and foxholes.

The Chuckwalla region includes the footprint of Camp Young, the Desert Training Center's first camp and its administrative core. Camp Young was primarily located south of present-day Joshua Tree National Park and north of Interstate 10 in the western area. While none remain standing, Camp Young boasted almost 100 administrative buildings, two hospitals, 50 warehouses, a theater, an officers' club, and a post office. Traces of the soldiers' lives at Camp Young can still be seen here, including rock-lined walkways and remnants of concrete foundations.

During his tenure at the Desert Training Center, General Patton lived at Camp Young but was in the field on a daily basis, including to review small unit training exercises in the Chuckwalla Valley. He would often shout orders into a radio while observing tank maneuvers from a hill overlooking the valley between the Orocopia and Chuckwalla Mountains, in the center of the Chuckwalla region's southern area. The road bulldozed for Patton's use to the top of this hill, known as "The King's Throne," remains clearly visible.

Against this backdrop of human history, the Chuckwalla region's many and varied plant and animal inhabitants have continued to persevere in the harsh desert environment. The region provides a refuge for more than 50 rare plants and animals, as well as 21 vulnerable vegetation communities. The diversity of biota has attracted numerous scientists over many decades who have conducted research into topics as varied as testing translocation methods for bighorn sheep, studying ant colony forming behavior, and documenting the demographic patterns of the Orocopia sage, a shrub with delicate lavender flowers that is only known to grow in the Mecca Hills and Orocopia and Chocolate Mountains.

The broad bajadas of the southern area radiate out from a series of small mountain ranges, whose sinuous canyons and ragged peaks provide habitat to a variety of species. The washes and sandy slopes of the Orocopia Mountains are home to Orocopia sage. The Mecca aster is endemic to only a small area, with more than half of its known occurrences located in the Mecca Hills. Mountain areas in the Chuckwalla region are also the only known locations of the recently described Chuckwalla cholla, a relatively low-lying cactus with reddish flowers.

Desert bighorn sheep, a sensitive species with declining numbers, live year-round on the craggy slopes of the Orocopia and Chuckwalla Mountains and are occasionally glimpsed in the Palo Verde and Little Chuckwalla Mountains. The broad, sandy washes that connect the mountains - unbroken by paved roads or large developments - provide the habitat connectivity necessary to preserve genetic diversity among bighorn sheep populations.

The region's expanse of gently sloping shrubby terrain is also vital to the survival of the threatened Agassiz's desert tortoise, encompassing key components of an essential corridor connecting the tortoise's Chuckwalla and Chemehuevi populations. Much of the region is critical habitat for this charismatic desert dweller.

Located in the southern area of the Chuckwalla region, the Chuckwalla Bench is an elevated area of alluvial fans that provided a setting for extensive study and monitoring of desert tortoises for decades. It is also home to over 150 native plant species. The specific species present change with elevation as the bench's slopes climb to an 80,000-acre expanse that rises to approximately 2,000 feet in elevation, resulting in an environment that is notably cooler and wetter than is typical for the Sonoran Desert. At the higher elevations, Mojave yucca and cholla become increasingly common. The Munz's cholla, a species endemic to the Chuckwalla Bench whose spiny, branching arms often reach a height of six feet, grows here.

In part because of the relative availability of forage and water, the Chuckwalla Bench is included in the United States Fish and Wildlife Service's primary area of interest for Sonoran Desert pronghorn reintroduction in California. In 1941, around the time that the United States Army began desert training in the area, the endangered Sonoran Desert pronghorn was last observed in the Colorado Desert in the vicinity of Salt Creek Wash, which runs between the Orocopia and Chocolate Mountains.

Dry washes in the Chuckwalla region are threaded with populations of desert trees including ironwood, blue palo verde, smoketree, and mesquite. These are known as microphyll woodlands, and they provide migration corridors for desert wildlife, as well as crucial habitat for migratory birds. Milpitas Wash, located south of the Palo Verde Mountains in the southern area near the Arizona border, is one of the largest remaining microphyll woodlands in the Colorado Desert. It is identified as a component of the National Audubon Society's Colorado Desert Microphyll Woodlands Important Bird Area. Old-growth blue palo verde trees in Milpitas Wash provide nesting cavities for an important population of Gila woodpeckers, which are listed as endangered under the California Endangered Species Act. Rare long-eared owls, Crissal thrashers, and black-tailed gnatcatchers also nest in Milpitas Wash.

Dense pockets of palo verde microphyll woodland occur in the northeast portion of the southern Chuckwalla region and are reported to have the highest winter bird densities in the California Desert. Sand dunes have dammed several small washes in the area, creating relatively wet conditions that are conducive to dense vegetative growth. These sand dunes in Chuckwalla Valley are fed by aeolian (windblown) sand transport corridors. In addition to the rich cultural sites associated with Ford Dry Lake, the portion of the Chuckwalla Valley in the eastern Chuckwalla region protects part of these sand transport corridors. The dunes in this area also provide habitat for the rare Mojave fringe-toed lizard.

Nightfall reveals another dimension of the Chuckwalla region. Kit foxes and sensitive species such as burrowing owls and elf owls emerge from dens, while a variety of rare bats including the California leaf-nosed bat, the western mastiff bat, and the western yellow bat dart through the desert sky. Mountain lions are also known to prowl the Chuckwalla region at night. A population of mountain lions in southern California and the central coast of California, which includes those in the Chuckwalla region, is currently a candidate species under consideration for listing under the California Endangered Species Act.

The Chuckwalla region encompasses striking geologic diversity, which both underpins the rich ecological and cultural values and is itself the focus of extensive research. In the far western reach of the southern area of this region, the Mecca Hills, shaped by the unquiet presence of the San Andreas Fault, attract not only hikers eager to explore their intricate canyons but a long line of geologists seeking to better understand fault dynamics. There is an exposure of Pliocene-Pleistocene terrestrial sedimentary rocks along the fault, and recent uplift and erosion have allowed the opportunity for its detailed analysis. Researchers have analyzed the Painted Canyon Fault, which lies within the San Andreas strike-slip fault zone in the Mecca Hills, to better understand tectonic processes along faults as far away as Denmark.

Just to the east of the Mecca Hills, the Orocopia Mountains have been the site of extensive study of the geologic mechanisms that shape the earth, including deposition, metamorphism, uplift, and exposure. In the late 1960s and early 1970s, the Orocopia Mountains were the site of field training for the Apollo 13 and 15 crews, preparing them to observe and document lunar geology.

In 1986, scientists documented five new species of mollusks from the Eocene epoch that were found in samples taken from the Orocopia Mountains, which helped clarify scientists' understanding of the timing of the westward migration of Eurasian mollusk species during the early Eocene and late Paleocene epochs. In the Palo Verde Mountains, at the southeastern edge of the Chuckwalla region, outcroppings of the Bouse Formation are helping scientists unlock mysteries around the formation of the Colorado River.

Protecting the Chuckwalla region will preserve an important spiritual, cultural, prehistoric, and historic legacy and protect places inscribed with history for future generations; maintain a diverse array of natural and scientific resources; and help ensure that the prehistoric, historic, and scientific resources and values of the region endure for the benefit of all Americans. As described above, the region contains numerous objects of historic and scientific interest, and it provides exceptional outdoor recreational opportunities, including hiking, camping, backpacking, rockhounding, sightseeing, nature study, birding, horseback riding, hunting, climbing, mountain biking, and motorized recreation, all of which are important to the travel- and tourism-based economy of the region.

WHEREAS, section 320301 of title 54, United States Code (the "Antiquities Act"), authorizes the President, in the President's discretion, to declare by public proclamation historic landmarks, historic and prehistoric structures, and other objects of historic or scientific interest that are situated upon the lands owned or controlled by the Federal Government to be national monuments, and to reserve as a part thereof parcels of land, the limits of which shall be confined to the smallest area compatible with the proper care and management of the objects to be protected; and
