Lost Creek Glacier

Lost Creek is a long glacier flowing on the northwest side of South Sister. It has substantial debris flow cover making the glacier appear smaller than it actually is. The air photo below is from taken in 2007. Other imagery is difficult to use due to heavy debris fall onto the glacier in the last two years, obscuring much of the ice.
