Opal Creek Wilderness

Opal Creek Wilderness features steep and rugged forested hillsides. The eastern portion of the area encompasses the headwaters of two major creeks (Battle Axe Creek and Opal Creek) which join to become the Little North Santiam River. The western portion of the area is dominated by two prominent peaks; Whetstone and Henline Mountains, which offer scenic vantage points and were once used as fire lookout sites. Opal Creek Wilderness can be reached via Oregon State Highway 22 and Marion County North Fork Road. The county road becomes Forest Road 2209 at the forest boundary. This road parallels the boundary of the western portion of the Wilderness.

The line is the average temperature and the bars are average precipitation at Detroit Dam, 9 miles from the center point at 1,220 feet, station USC00352292 in the NOAA monthly climate normals for 1991 to 2020. Precipitation totals about 94 inches a year. The dotted line is average snowfall, about 10 inches a year on the same inches scale. The station sits about 2,500 feet lower than the center point, so temperatures on the ground run cooler.

Large units span more than one climate. The station stands in for the center point, and the outer parts of the boundary can be warmer or colder.
