MOUNT WASHINGTON (OREGON)

'Mount Washington' is a shield volcano in the Cascade Range of Oregon. The mountain dates to the Late Pleistocene. However, it does have a line of basaltic andesite spatter cones on its northeast flank, which are approximately 1,330 years old according to carbon dating. The main peak is a volcanic plug that was heavily eroded by glaciers in the last ice age.^[1]
Climbing Mt Washington is an easy daytrip(3-6 hours to summit), however caution is necessary as the volcanic rock is loose and rotten. The easiest route is via the North Ridge. Access via the Pacific Crest Trail near Big Lake. Hike through 2 miles of forest trail up to the ridge. Stay east of rocks up to summit block. Climb through chimney past leftover rappel slings and scramble up summit block about 100 yds. Class 4 climbing- rope and climbing knowledge preferred.
