Writing on the Wall
Crow Country’s Ancient Records
BY MICHELE MURPHY
People flocked to Pictograph Cave State Park last year, doubling attendance from the previous year. Interest in the site may be growing, but it’s nothing new. The three caves—Pictograph, Middle, and Ghost—have been luring people for more than 9,000 years.
The natural shelters are nestled in a sandstone bluff on a well-traversed path extending south from the confluence of Bitter Creek and the Yellowstone River, 6 miles south of Billings. The cave complex has long been a site of mystical power, a culturally significant gathering place for American Indians. On the interior wall of Pictograph Cave (the only one containing rock art), archaeologists discovered more than 100 pictographs, painted between 2,145 and 200 years ago. They also found stone and bone tools, moccasins, arrow shafts, basketry, grinding stones, and fire-starting tools. Excavations turned up jewelry too, such as pendants, bracelets, and beads beautifully crafted of seashells acquired from Pacific Coast Indians.
“It’s an amazing assem-blage of artifacts,” says Montana Fish, Wildlife & Parks archaeologist Sara Scott. “It’s information about life in prehistory, and it builds a picture of who these people were.”
The site also offers a newly opened visitor center that complements the park’s picnick-ing, hiking, wildlife watching, and educational opportunities.
Scientific documentation of the cave’s contents began in 1937. Archaeologist H. Melville Sayre, president of the Montana Society of Natural History and an instructor at the Montana School of Mines in Butte, inves-tigated artifacts found by local residents at Pictograph Cave, then known as Inscription Cave. In this largest of the cave trio, a Works Progress Administration crew documented 106 rock art images painted in white, black, and red. At the time, archaeologists did not fully realize the significance of pictographs. (The Lascaux Cave paintings in southwestern France were not identified until 1940, setting off worldwide interest in rock art.) But Sayre and his crew apparently knew they had found something significant and made full-scale drawings of the images.
Sayre brought in an amateur archae-ologist, Oscar Lewis, and, with the help of WPA workers, they undertook a major exca-vation, uncovering tools, jewelry, animal bones, and hearths of ancient fires. (A dotted black line, still visible in Pictograph Cave, marks soil levels before the excavation.) Trained archaeologist William T. Mulloy replaced Sayre in 1940 and took the lead in the excavation. According to rock art expert and retired New Mexico State University anthropology professor Lawrence Loendorf, Mulloy contributed significantly to archaeology when he devised a chronology based on where artifacts were found in successive layers on the cave’s floor and how the artifacts’ technologies changed. “Archaeologists in the Northern Great Plains are still using his chronology to date the artifacts they find,” Loendorf says.
The excavation and Mulloy’s study ended in 1941 with the advent of World War II. By then the WPA-funded project had yielded more than 30,000 artifacts from Pictograph and Ghost caves and the area below the caves, named by early white settlers—ironically, as it turned out—Empty Gulch.
For the next several decades, the cave complex was neglected. Vandals carved into the rock art and covered pictographs with graffiti. Teenagers held beer parties at the sacred site. Pickups and four-wheelers tore across the fragile landscape. Meanwhile, thousands of artifacts were lost or stolen from a museum built (since removed) at the cave complex in 1939 and other storage sites.
Grasping the importance of the Pictograph Cave complex, former Billings mayor Willard Fraser and other local preservationists convinced the National Park Service in 1964 to designate the site as a National Historic Landmark. The area was managed by the city of Billings until 1969, when it was named Pictograph Cave State Historic Site by the Parks Division of what was then the Montana Fish and Game Depart-ment. In 1991 it became Pictograph Cave State Park. Over time the department landscaped the site, built a hiking trail and picnic area, and installed outdoor interpretive panels.
Unfortunately, the majority of the park’s namesake pictographs have all but disappeared. The combination of vandalism, natural fading, and water damage has affected roughly 85 percent of the rock art images. That makes the replications from the late 1930s especially valuable. “Otherwise, we’d have no record of the many pictographs that are no longer visible,” says Darla Bruner, Pictograph Cave State Park manager. Visitors can view the reproductions on outdoor interpretive signs and throughout the visitor center.
The park offers many other amenities. Bruner considers the cave complex a living museum of natural history—the rare place where rock art remains accessible to the public—roughly 20 pictographs are still visible—and where visitors can immerse themselves in the site’s historical and sacred significance. For much of the year, the park bustles with activity. Visitors view the remaining rock art images in Picto-graph Cave and try to sense spirits in Ghost Cave. Many follow the short hiking trail, looking for birds and other wildlife. Over 60 bird species have been documented at Pictograph Cave State Park, making it a designated stop on Custer Country’s Southeastern Montana Birding Trail. Visitors commonly see wild turkeys pecking the ground for insects, red-tailed hawks soaring overhead, and songbirds flitting among shady cottonwoods.
In spring and fall, bus loads of inquisitive schoolchildren come to learn about the rock art and the people who created it. On Halloween, visitors gather for a campfire in the picnic area, and Bruner leads a flashlight hike along the trail. In winter, Pictograph Cave State Park is a quiet place of refuge and solitude, snuggled against the snow-dusted rims and visited primarily by jackrabbits, mule deer, coyotes, and the occasional bald eagle straying south from the nearby Yellowstone River.
This May, says Bruner, Crow Indian interpreters erected a traditional tipi at the park. The Yellowstone Valley Amateur Astronomers will offer public stargazing opportun-ities—in late August, and again in mid-October.
Loendorf, who grew up in Billings, says he spent memorable days as a boy exploring Pictograph Cave. He continues to visit whenever he’s in the neighborhood. “There are other places [in the West] with more visible rock art,” the anthropologist says, “but Pictograph Cave has easy access and a pristine setting. You get a sense of the open space and the caves as they existed thousands of years ago.”
Another longtime visitor is Barney Old Coyote Jr., of Billings. The Apsáalooke (Crow) elder and historian visited the cave complex as a boy and remembers meeting Mulloy. He says the archaeologist hired his father, Barney Old Coyote Sr. as an interpreter so that Apsáalooke elders could help explain the picto-graphs. “Some of the drawings were so old even the elders couldn’t identify them,” Old Coyote recalls.
Pictograph Cave has been here since the beginning of our tribal memory.” According to Old Coyote, the Apsáalooke believe Pictograph Cave is a place with great power, where war parties and hunters left offer-ings and sought blessings for their ventures. “They didn’t question the source of the power,” he says. “They acknowledged the power and honored it. We still do.”
Apsáalooke phrases refer to Pictograph Cave as Ammaáhpawaalaa-tuua (“Where there is rock writing”) and Alahpaláaxawaawaalaatuua (“Where there is ghost writing”). The cave complex sits in the heart of traditional Crow country that once extended from Wyoming’s Wind River north to the Musselshell River, and from the badlands of eastern Montana west to the Crazy Mountains.
A new sandstone-hued visitor center that opened in 2009 is the park’s latest attraction. Inside the 2,900-square-foot, energy-efficient building are interpretive displays, restrooms, a gift shop, and a meeting room. The displays contain replicas of arrowheads, dart points, and spear points found at the site at different periods of human occupation. (The originals are stored at the Montana Histor-ical Society and other facilities.) The oldest and most intricately detailed projec-tile, an ivory-colored point likely lashed to the end of a hand-thrown hunting spear, dates back nearly 9,000 years. A small, sharp obsidian point represents the most recent period of occupation, from roughly 1,500 years ago until about 150 years before the present. The size and shape are consistent with smaller arrowheads used by hunters on horseback.
Another artifact replica is a diminutive black turtle effigy, the size of a quarter, carved into a charred bone. Turtles, a symbol of longevity, were believed to represent the connection between the natural and spiritual worlds. In 1993, a small sample from another turtle image was removed from the wall inside Pictograph Cave. Radiocarbon analysis of the sample determined it was 2,145 years old, making it one of the oldest documented rock art images on the Northern Great Plains.
Bruner explains that the “BP” on the dates of many artifacts means “before present.” Scientists use 1950, the year that calibration curves for radiocarbon dating were established, as an arbitrary “present” date on which to base a time scale used in archaeology, geology, and other scientific disciplines. For instance, the oldest projectile point is dated around 9200 bp, or 9,200 years before 1950.
After more than half a century’s absence, archaeological work is again under way at the cave complex. “In compliance with the Montana Antiquities Act, we frequently hire archaeological contractors to conduct investigations before going ahead with any projects that might disturb the ground,” says Scott, the FWP archaeologist. In 2007, the department hired Steve Aaberg, owner of Cultural Resource Consulting Service, to perform test excavations at the sites of the proposed visitor center and new trail improvements. One discovery was an 800-year-old cooking hearth that contained a charred bison bone “We got lucky,” says Aaberg. “There’s a tendency to think the Pictograph Cave story has been completely told, but that’s not so.” The archaeologist believes even more artifacts lie buried deeper than what was previously excavated.
Aaberg says he greatly admires the hunter-gatherers who occupied Picto-graph Cave. “The civilizations that left behind massive structures like pyramids and temples have come and gone, while the hunter-gatherer peoples continued to survive until relatively recently—and in some parts of the world they still survive,” he says. “To me, the remarkable knowledge that hunter-gatherers had of their complex natural envi-ronment—along with their cultural longevity and the light footprint they left on the landscape—make them as advanced as any other culture.”
Fortunately, previous visitors to the cave complex left some trace of their passing. Their artifacts and rock art continue to attract people to Pictograph Cave State Park, a site of sweeping scenic beauty and rich historical significance. Visitors can still smell the fragrant sweet sage in the summer breeze and gaze upon the rimrocks and vast plains framed by a bright blue sky. And they can know they are at an important place where others have visited for thousands of years—and will continue to visit for many years to come.
