Mountaineer Peak: Another Mission Mountain Glacier Gone

Mountaineer Peak in Mission Mountains

This photo shows Mountaineer Peak and the remains of what was an extensive glacier (center of photo) - if you were to hike there today you would note glacial striations (elongated gouges in the soft sedimentary rocks) in the now exposed “ramp” below the ridge line extending to the right from below the summit. Striations result when the ice, as it moves, drags imbedded rocks along the bedrock.
