NF Shuksan Approach BETA: from base of chair 8 where most folks descend down old clear cut to lame valley schwack go uphill about 200 ft to rounded cattrack turn on climbers left side of cattrack/chair 8 run. From there, take sharp left, leaving ski area boundary, traversing perpendicular across slope for a few hundred feet. You will do a bit of schwacking and cross an unpleasant gully or two before the forest will open up to what we dubbed the, "magic carpet ride." An open snow slope/gully which heads quickly and easily down and left to the bottom of the white salmon glacier basin.
At least that's how it worked about 8 years ago. Super cruiser overall. The terrain may have changed, but it's definetly worth a look.
