Thanks to theyogiclimber for adding this peak.
Crater Mountain is located 3 miles SE of Jack Mountain in the western margin of the Pasayten Wilderness. The mountain is volcanic greenstone and has a fire lookout. The Jerry Glacier occupies the northeast cirque on the mountain. The peak can be seen from several locations along the North Cascades Highway.
"Travelers heading northwest on Highway 20 where it follows Granite Creek view the great mass of Crater Mountain rising 6,000 feet above the valley bottom of Canyon Creek. To enjoy the same view, however, east-bound travelers should stop at a the viewpoint and sign (located 11.6 miles from the Western Ross Lake Overlook; or 11.0 miles from Rainy Pass,) and look back the way they came.
Crater Mountain is carved from greenstone of the Hozomeen Terrane, once the basaltic floor of the ancient Methow Ocean. The mountain’s name probably derives from the craterlike shape of its summit, which was carved from the ancient metamorphosed basalt by modern cirque glaciers. Crater Mountain is not a volcano with a summit crater. The rugged battlements of the greenstone viewed from the highway rest above phyllite of the Little Jack terrane, which is exposed in the lower slopes of the mountain. The thrust fault that separates the two terranes here was one of the first such faults discovered in the North Cascades by the late Peter Misch." - USGS
