Bonkers was a favorite powder haunt of the helicopter ski operations back before this area was designated as wilderness. Now it's only available to the backcountry skiers willing to put in the time and effort to hike in to it. It's a very worthwhile run if you're looking for a long, wide, open area with plenty of room to turn. It's a pretty straightforward ascent and descent with most parties putting in a nice tight skin track up the lookers right to gain the ridge. The upper slopes are in the mid to upper 30 degree range, then it mellows out quickly to a very enjoyable powder skipping pitch. If you ski all the way down to the flats it's nearly 2,000 feet long! A great spot to put in a few laps, but tricky to navigate when it's cloudy since there aren't any trees to help with visibility.
