Fort Rock

In 1938, an archaeologist from the University of Oregon named Luther Cressman was digging in a small cave near Fort Rock when he uncovered dozens of sandals woven from shredded sagebrush bark. They lay beneath a layer of volcanic ash, ash that geologists later matched to the eruption of Mount Mazama, the blast that formed Crater Lake about 7,600 years ago. Whoever left the sandals had done so before that eruption sealed them in.

Cressman was sure they were ancient, but he had no way to prove how ancient, because radiocarbon dating had not yet been invented. When the method finally arrived, fibers from the sandals themselves were dated in 1951 to more than nine thousand years old, and later work pushed the oldest close to ten thousand. They remain the oldest directly dated footwear in the world. To stand at Fort Rock is to stand where people were making and wearing shoes at the end of the last ice age.

Those sandal-makers were among the ancestors of the Northern Paiute, who lived across this high desert for thousands of years, moving with the seasons to hunt, fish the marshes, and gather roots and seeds. Fort Rock and its valley were part of a landscape they knew intimately long before any map put a name to it.

The most recent chapter is a shorter and sadder one. In the early 1900s, promoters and a federal homestead act lured hundreds of families onto the Fort Rock Valley flats with the promise of free farmland. For a few years there were schools, stores, and even a newspaper. But the high desert is dry and the winters are hard, and within a couple of decades most of the homesteads had failed and emptied out. A cluster of those original cabins and buildings has been gathered and preserved at the open-air Fort Rock Homestead Village Museum in the little town nearby.

Fort Rock is what geologists call a tuff ring, born of an explosive marriage of fire and water. Sometime in roughly the last hundred thousand years, basaltic magma rising toward the surface hit the wet mud beneath a shallow lake and flashed it to steam. The blasts threw out rings of ash that hardened into the rock you see today, welded ash that geologists call tuff.

The lake did the rest of the sculpting. For thousands of years, a great Ice Age lake known as Fort Rock Lake filled this basin, and its waves gnawed at the soft volcanic walls, cutting the terraces and notches that still band the cliffs. The waves eventually breached the south side of the ring, which is why Fort Rock stands open like a horseshoe today rather than a closed circle. When the climate dried and the lake vanished, it left the rock marooned on a plain of sagebrush.

The sheer inner walls of Fort Rock are prime real estate for birds of prey. Prairie falcons and golden eagles nest on the ledges, along with hawks and owls, and parts of the rock are closed to climbers in spring so the raptors can raise their young in peace. Watch for them riding the updrafts along the cliffs.

Out on the flats it is classic Great Basin high desert: sagebrush and rabbitbrush, pronghorn and mule deer, jackrabbits and coyotes, and the small birds of the sage such as the sage thrasher and the horned lark. The country looks empty at first glance and turns out to be full of life once you slow down.

Spring is the gentlest season, when the desert greens up, wildflowers appear in the sage, and the nesting raptors are active on the cliffs. Some routes close to climbing then to protect the birds.

Summer days are hot and bright, and the nights cool off fast at this elevation. It is a fine time for the short walk around the base of the rock, best in the soft light of early morning or evening.

Fall brings crisp air, golden light, and the deep quiet that the high desert does best.

Winter is cold and can be snowy, and the roads out here are remote, but a dusting of snow on the red-brown rock and the huge desert silence are their own reward. Come prepared and check conditions before you go.

Fort Rock is a striking volcanic formation that rises like a ruined fortress from the flat high desert of central Oregon, a near-circular ring of jagged rock walls hundreds of feet tall. It formed tens of thousands of years ago when lava erupted upward through the bed of an ancient lake, and the result is one of the most dramatic and unexpected landmarks in the Oregon desert.

Yes, an easy loop of a bit over a mile runs along the inside of the great rock ring, gaining just a little elevation, and it can be walked in under an hour. Interpretive signs explain the geology, desert plants and jackrabbits are common, and raptors often nest in the cliffs. Wear sturdy shoes and bring water, since the trail is exposed with no shade.

The famous sandals, woven from sagebrush bark and among the oldest footwear ever found at around nine to ten thousand years old, were discovered in a cave near Fort Rock. That cave is protected and can only be seen on a limited guided tour rather than on your own, so if it interests you it is worth looking into a tour in advance. The sandals themselves are held in a museum collection.

Spring and fall are the most comfortable, with wildflowers in spring and golden rabbitbrush in late summer, since the high desert bakes with no shade in the heat of summer. Fort Rock is also far from city lights and makes a wonderful spot for stargazing after dark. Whenever you go, bring plenty of water and sun protection, and a layer for the cool desert evenings.

Nearby, the Fort Rock Homestead Museum gathers original pioneer buildings from the surrounding valley into an open-air village that tells the story of the hardy families who tried to homestead this dry country. Between the rock, the trail, the cave's ancient history, and the museum, the little community of Fort Rock makes a rewarding half-day detour into Oregon's remote outback.
