Bighorn Sheep Hunting in Unit 570

Where to Find Bighorn Sheep in Unit 570

Bighorn sheep in Oregon occupy steep, rocky escape terrain with reliable forage on adjacent benches and slopes. Herds tend to stay close to the cliffs and rimrock that give them security from predators.

Escape Terrain

Focus glassing on the rim faces, talus slopes, and broken rock features of the unit. Rams often bed where they can see long distances and drop into cliffs if disturbed.

Benches and Grass Basins

Between feeding sessions, sheep use grassy benches near the edge of steep terrain. Early and late in the day they pull out into more open ground to feed, then retreat to bed in rougher country during mid-day.

Water and Travel Corridors

Springs, seeps, and small drainages within sheep country act as consistent travel corridors. Glassing these spots patiently from a high vantage is often more productive than still-hunting through the rocks.

How to Hunt Bighorn Sheep in Unit 570

Oregon bighorn tags are rare and valuable. Plan on multiple days of glassing and be prepared for technical terrain.

Scout with Optics

High-quality binoculars and a spotting scope are essential. Glass long and systematically across rock faces and benches before ever moving.

Mature Ram Identification

Take time to judge rams carefully. Oregon sheep hunts are once-in-a-lifetime opportunities for most hunters, and picking the right animal matters.

Technical Terrain

Shots and pack-outs in sheep country can be dangerous. Bring a partner if possible, plan safe routes, and carry proper gear for steep ground.
