The Sahale Peak Quien Sabe Glacier climb presents a moderate challenge and is situated in Boston Basin among other classic peaks such as Forbidden Peak, Sharkfin Tower and Boston Peak. Quien Sabe Glacier lies to the west of the ridge between the two peaks while the Davenport Glacier is in a cirque east of this ridge.

Quien Sabe Glacier via Boston Basin • 3 Day Ascent

Sahale Peak is also referred to as Sahale Mountain. The ascent climbs the steep Quien Sabe Glacier to the Boston Sahale Col and traverses the final exposed rock and snow ridge to the summit. We have the option of descending the route or traversing the peak to Sahale Glacier and descending the Sahale Arm to Cascade Pass. On the approach we climb steeply through heavy timber crossing a number of small streams which eventually give way to the beautiful alpine basin known as Boston Basin. Our professional guides will introduce and teach you the skills necessary to make a safe and successful climb.

Boston Basin Approach

  • Approach Time to Camp: 3-4 hours
  • Distance: 3-4 miles, 2100 ft. gain
