Leaving the Mountaineers Creek trailhead make your way South on the Stuart Lake trail. Before long the valley will start heading Southwest and will pass by the Colchuck Lake trail but make sure not to go on it. Soon enough the Valley will split into a Y with the trail still going west but you need to start heading South. From my memory crossing Mountaineers creek was quite easy and once on the Southern branch stay on the lookers right side. Follow the valley floor up the main creek and before long it will wrap west into a small basin divided by the Northeast ridge of Sherpa Peak.

If you followed the route correctly you should be at the base of the Sherpa Glacier with your ascent route directly south of you. Start off skinning as you gain elevation all the way to the base of the couloir. Soon enough you will have to switch over to cramponing until gaining the ridge and being on top of your line. If you want to add some extra vert you can climb to the false summit of Mount Stuart.

The descent is perfect fall line all the way into the valley before following your skin track back to the car. The moment you are back in the basin you will have to skin as it is flat terrain but at least things should go relatively fast as you had set in the trail earlier. We did this route in Early May as a day trip but it would be a little bit less hectic if done as an overnight trip.
