Use the Blackcomb Gondola to gain most of the elevation and then either the Matt Gunn scrambling route over the Broken Towers, or go up Body Bag Bowl and boulders. Spearhead should be an easy addition from Blackcomb. See https://www.facebook.com/groups/240069949775049/posts/1218370725278295/ for a description of the Broken Towers approach.

I'm mostly interested in taking pictures of the Spearhead Glacier and Decker Glacier to note where the crevasses are for the winter. 

About a 1000m gain day, 10km return. 

Given that first gondola is at 10am and last is at 5pm, we only have 6.5 hours max. Will have to move at a good clip to make it back in time. 

Keep in mind that you have to buy a summer hiking pass to use the gondola unless you have an Epic pass.
