Big Blue is in the second valley from the south on the east side of the highway - opposite the valley from summit creek. Big blue was a little hanging glacier that is actually gone now so you won't find that land mark anymore - and its about 8 kms up the valley. You go up the valley often starting at the white outhouses parking lot and then turn right when the valley forks and go past a couple of lakes to get to big blue. The photo looks like it could be any of the two valleys on either side of the big blue valley. Perhaps ask the YAA avalanche techs for the specific location where the video/photos were taken if you need more then that. Thanks
