What does the south side of Tyndall look like?

I'm in the middle of putting together a custom "high route" for the summer and after coming over Junction Pass, we'll be at Shepherd Pass below Tyndall. With the "easy" slope up in front of us we'd love to do a traverse to lake 3645 on the other side.

Bob Burd has a trip report online that suggests that "in fact a climb from the Wright Lakes Basin to the south only rates class 2", but he was headed to Vermeer so there aren't any photos to show details of that south route.

We'll be there with large packs having come from Yosemite and no real interest to do technical stuff. Reading his report, it seems that the route may be harder than class 2. Here's a map and his story from that trip:

I feel the easy route down probably drops down from the summit much earlier than he did, so the sketchy class 4 stuff he encountered may not be part of the normal route.

Our plan is to head from Tyndall's summit south down to Wright Lakes, from where we'd head down to the JMT, but we'll only take on Tyndall if I we can get down the south flank without any major obstacles.

This is the best image I have found so far showing the side of Tyndall we'd have to descend, but other than the slope angle, I can't really make out any details: http://www.snwburd.com/bob/trip_photos/barnard_1/DSC00030_w.html
