Thomas Condon Paleontology Center

The John Day country has been home to Native peoples for thousands of years. The Tenino and Umatilla bands of the Columbia Plateau and the Northern Paiute of the Great Basin used this valley and the surrounding uplands, and the monument's own Picture Gorge takes its name from the pictographs painted on its rock walls. Their descendants are enrolled today in tribes including the Confederated Tribes of Warm Springs and the Confederated Tribes of the Umatilla Indian Reservation, and this remains a homeland, not merely a fossil site.

The center is named for Thomas Condon, a nineteenth-century minister and self-taught scientist who became the first person to recognize what the John Day beds held. During the Civil War era, soldiers and settlers brought fossils they had found in the valley to Condon in The Dalles, and he understood at once that they were extraordinary. He collected and studied them, corresponded with leading paleontologists on the East Coast, and did much to bring the John Day fossils to the world's attention. He went on to become Oregon's first state geologist and a founding professor at the University of Oregon.

Ranchers shaped the valley too. In 1910 the Scottish immigrants James and Elizabeth Cant bought land along the John Day River and raised sheep and cattle here, building the white ranch house in 1917 that still stands within the Sheep Rock Unit. The Cant Ranch operated until the National Park Service acquired it in the 1970s, and its buildings now interpret the ranching history of the valley alongside its far older story.

The monument itself was established in 1975 to protect the fossil beds, and the present Thomas Condon Paleontology Center opened in 2005, giving the collections a modern home with room for research, storage, and the public all under one roof.

The fossils here span an immense stretch of time, and they are unusually continuous, so that geologists can read one age after another stacked up in the surrounding hills like pages in a book. That is what makes the John Day beds world-famous, not a single spectacular find but the sheer, unbroken length of the record they preserve through the Age of Mammals.

The layered hills around Sheep Rock themselves tell a volcanic story. The dark caps on the ridges are basalt from ancient eruptions, while the softer, banded slopes below are ash and clay laid down over millions of years, colored greens, tans, and reds. Sheep Rock, the landmark that gives the unit its name, rises across the valley from the center, a striped monolith topped in dark rock.

The specimens on display, and the far larger number kept in the collections behind the glass, record how life in Oregon changed as the climate cooled and dried. Lush subtropical forests gave way over the eons to open savanna and finally to sagebrush country, and the animals changed with them. The galleries make that slow transformation visible, backed by large murals that reconstruct each vanished world.

Outside the museum walls, the John Day River valley is high-desert ranch country, wide and dry, framed by colored bluffs and dark basalt rims. The John Day River is one of the longest free-flowing rivers left in the country, running undammed for hundreds of miles, and it threads green through the sagebrush along the valley floor.

This is big-sky wildlife country. Mule deer and pronghorn range the uplands, bighorn sheep pick their way across the rimrock in places, and golden eagles and prairie falcons ride the thermals above the bluffs. Along the river, beaver work the banks and songbirds crowd the cottonwoods and willows, a green ribbon of life through the dry country.

The trails that lace the Sheep Rock Unit, including the walk up Blue Basin, lead into eroded, blue-green badlands where fossils weather out of the ground and the scale of the geology becomes plain. The museum tells the story indoors, and the surrounding country lets you walk straight into the rock it came from.

Spring is one of the finest times to visit, with mild days, green in the valley bottoms, and wildflowers on the slopes, all before the summer heat settles in.

Summer is hot and dry in the high desert, and the exposed fossil-bed trails bake in the afternoon, so early mornings are best, with the air-conditioned museum a welcome refuge in the heat of the day.

Fall brings cooler air, golden cottonwoods along the river, and some of the clearest, most comfortable weather of the year, with thin crowds in this already quiet corner of the state.

Winter is cold and stark, and snow can dust the colored hills for a striking effect, though the center runs on reduced seasonal hours and the remote roads demand more care.
