Located roughly three hours drive north of Truckee, Mt. Lassen is the southernmost volcano in the Cascade Mountain Range. Lassen was last active from 1914 to 1921. With a summit elevation of 10,450 feet, Mt. Lassen offers many fine options for ski mountaineering. Here is footage from a single day assault of the Northeast Face on June 26, 2010. During our ascent and descent we crossed a large swath of devastation from a massive avalanche that occurred this past winter. Hundreds of trees upwards of forty feet tall were leveled like matchsticks. Reports of the debris began coming in to park officials in late March but the actual date or even month of the slide is unknown. A park ranger informed us they are calling it a fifty year type of event.
