3 of us sumitted on a day that included 3+ inch new snow. Lower portion of BMB trail still packed out from previous parties but about halfway to Range Trail, new snow required trailbreaking and beyond the balanced rock, trail difficult to follow - use caution there. From Range trail jct, drifting new snow, difficult route finding and a few spruce traps makes going slow - again use caution. Carried crampons but no need to use. 4 ft+ unconsolidated snow above 3800 ft.
A few people also did Armstrong and egressed via BMB trail. Unlikely that any broken trails above 3800ft will remain that way, given frequent new snows and wind drifts.
