Agnes Mountain

Agnes Mountain is a dramatic, but relatively unknown, peak in the North Cascades of the US state of Washington. It is not of regionally high elevation, but it rises steeply from low footings; Beckey calls it "an immense Matterhorn-shaped massif." For example, its north face drops 1,800 feet (549 m) from the summit to Agnes Creek in only 1.5 miles (2.4 km).

Agnes Mountain was climbed first in 1936, by W. Ronald Frazier and Dan O'Brien. They ascended from the West Fork of Agnes Creek. The second ascent was not until 1969. The recommended route in Beckey's guide first follows the Northeast Ridge of nearby Asa Peak, then traverses to the south ridge of Agnes, which involves some short technical sections (up to class 5.6).

Due to its location deep in the North Cascades, its difficult approaches, and the fact that it is not particularly high, Agnes is seldom climbed. Beckey notes that "only fourteen parties succeeded by 1987."
