The setting is awesome for this one, located right under the Diamond at the start and ending on the Loft. It gets into the steep 40°s and is fairly consistently graded all the way through. Broadway can be accessed about 2/3 of the way up if you're looking for even more serious stuff. To get to the bottom (Mills Glacier), cross or skirt around Chasm Lake. This is on the looker's left side of Longs' huge East Face.
