Hiking to see pictograph art in Horseshoe Canyon, Utah

HORSESHOE CANYON, Utah — In a remote arm of Canyonlands National Park, deep inside a warren of rock and sand, is one of the greatest and most mysterious collections of ancient art in North America.

Towering, enigmatic pictographs, some more than 6,000 years old, stare down from stone walls, their meaning unknown yet their allure universal.

This is Horseshoe Canyon, one of the loneliest places you're likely to find in this country, nestled amid southeast Utah's labyrinth of slickrock, arches and desert.

I had explored Canyonlands before but never Horseshoe, notorious for its unforgiving terrain.

But last year I decided it was a risk worth taking and, better yet, a risk worth taking with my two children, who were yearning for a bit of adventure after a long, cold winter.

So on a crisp morning we drove six hours from our home near Boulder, Colo., to Moab, Utah, where we spent the night before heading out early the next day.

We traveled west on Interstate 70 past Green River to the Hanksville exit and then took Highway 24 to a dirt road where a sign pointed the way to Horseshoe Canyon.

Parts of the road were covered in sand that quickly turned to brutal washboard, reducing my two-wheel-drive Kia to about 5 mph.

We were then surrounded by cows — desert cows — staring blankly at us. I honked and they lumbered out of the way, sending my then 10-year-old daughter, Theodora, into gales of laughter.

Three hours after leaving Moab we reached the trail head.

It was 9 a.m. and already hot. We donned hats, loaded our backpacks with water and began the 6.5-mile round-trip hike with a 750-foot descent to the canyon floor.

It was a forbidding place. Yet as the canyon walls closed around us, a streambed appeared with a trickle of water running down the middle. There were rabbit and bird tracks. Cottonwoods sprang up, their spreading limbs shading us from the withering sun.

The stream now widened to more than 10 feet, and the canyon grew lush and green.

"Look up there!" yelled my son, Nicholas, then 15, charging up a steep hill. There were two dozen paintings, or pictographs, high on the canyon wall.

They were strangely shaped with neither arms nor eyes and standing up to 4 feet high. One figure had feathers dangling from his arms. There were insect-like creatures and butterflies. Were they men, spirits, symbols? No one knows, so scientists refer to them as anthromorphs and describe the art as Barrier Canyon style, after the original name of this place.

The National Park Service calls this panel the High Gallery and says it predates the Anasazi and Fremont people who once inhabited this land. That could make it more than 6,000 years old.

The creators are known as the Archaic People, a hunter-gatherer race lost to antiquity. As mysterious as they are, the bigger question is what it all means. Was this perhaps a sacred place to embark on vision quests or perform religious rites?

"We think they traveled in small bands of between five and 15, and at different times of the year they would get together in one place to celebrate their traditions," said Gary Cox, a ranger and archaeological technician in the Maze district of the national park. "The pictographs are telling their stories. What those stories are and what the pictographs mean is really not known."

We rushed back across the stream after spotting another set of images beneath a sandstone overhang. There were ocher and pink anthromorphs, bison heads and beetles. The paint, experts say, was made by mixing the iron oxide in the rocks with clay.

A few yards away red, white and yellow handprints appeared, conveying a remarkable sense of intimacy. We resisted the urge to place our hands atop theirs in order to make contact with these people across millenniums.
