Mark O. Hatfield Wilderness

Known as the Columbia Gorge Recreation Area prior to Wilderness designation, this area lies just south of the sheer cliffs of the Columbia River Gorge. Most of the land adjacent to the river and along Interstate 84 is privately owned and often developed and, of course, outside the Wilderness boundary. The breaks of the gorge are spectacular basalt cliffs, rocky slopes, and rock outcroppings. Rugged and steep, the slopes of the Wilderness rise to a slightly uneven plateau and on to mountain peaks, talus slopes, and lakes with elevations ranging from approximately 100 feet near the river to 4,900 feet on Mount Defiance.

The line is the average temperature and the bars are average precipitation at Bonneville Dam, 4 miles from the center point at 62 feet, station USC00350897 in the NOAA monthly climate normals for 1991 to 2020. Precipitation totals about 80 inches a year. The dotted line is average snowfall, about 10 inches a year on the same inches scale. The station sits about 2,000 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.
