OR Bighorn Sheep Unit HEPPNER — Heppner

OR HEPPNER — Tactical Analysis. Terrain & Access Heppner spans 1,773–5,932 feet across mixed terrain, from lower-elevation shrubland and grassland to alpine ridges. With 35% public land, the unit is predominantly private — access is the defining constraint. Lower elevations support sagebrush habitat and open country; higher zones offer alpine and subalpine terrain where bighorn sheep concentrate. Elevation relief is substantial and unforgiving; expect steep drainages and sustained climbing in productive sheep country. Trophy Potential The unit holds a limited but legitimate bighorn sheep record: one sheep scoring in the high 170s appears in the county records..
