At Drinkwater Pass, about fourty miles east of Burns, Oregon, Highway 20 crosses a narrow gap between huge ancient lava flows. To the south they form rimrocked rolling tables isolated by a 16 mile deep bend in the Malheur River. Grass grows tall here and views fall away into forever. Below the cliffs, if you can find a way through, the land changes abruptly into powdery white deposits left by ancient oceans. Intricate mazes of eroded hills hide springs of surprising flow and beauty. To the southwest six- mile long Warm Springs Reservoir shimmers in the desert sun.

Sample Pack Trip: ALTNOW GAP

Beginning at Drinkwater Pass this trip takes us out onto the high reaches of Carrey table. Broad expanses of native grass, sagebrush and scattered junipers frame vistas of distant Steens Mountain and the rolling country between. In the spring, bighorn sheep can be spotted here. Sage grouse are a possibility and pronghorn are common. The route uses old jeep trails and cattle paths to move us across the rocky country before dropping through massive rimrock cliffs to the powdery ancient seabed soils below. On Day One we work our way across the northern expanse to Alnow Gap, a narrow saddle between the tables. Day Two takes us through the rimrock and down to the Malheur River. We then wind north through hills that once comprised ocean floor. On Day Three we climb out of the hills and return to Drinkwater Pass.
