The approach depends on where you start. It is probably most common to start from the Longs Peak Trailhead: Starting from the Longs Peak Trailhead, hike up to Chasm Lake and from there to the base of Chasm View Wall. However, on this trip Nate and I started from the Boulderfield, since that is where we were camping: Starting from the Boulderfield, hike to the ridge connecting Mt. Lady Washington to Chasm View. Either descend the
Camel Gully or for a more direct but lesser known approach descend
"Fifth Avenue" directly to the base of Chasm View Wall (we descended
"Fifth Avenue").
Note: There seems to be a bit of confusion as to the exact Fifth Avenue route and route name (alternative names include
Fisherman's Folley, Fisherman's Fantasy, 42d Street, Positively 4th Street). I was psyched to be able to gather some beta for the
Fifth Avenue connector route between the Boulderfield and Chasm Lake Cirque. It is definitely the most efficient way to the base of Chasm View Wall from the Boulderfield. I added some photos (the ones with green headers and annotations) to my
Diamond Beta Page.
