The rock is compact and polished; not much in the way of handholds or gear. The first half of the climbing, up into the basin, did not feel highly threatened to me; there is a lot of lower angle rock between the snouts of the glaciers and that area. The upper slab section, which we found entirely unprotectable and lies in the fall line of the right-hand glacier, might be avoidable climber's right (looking at some other photos), but you do still have to pass the fall line of that right ice cliff. Doing so on class 2 or 3 would be faster though, than the 4/5 we encountered. You'd have to cross the larger, right-hand outflow twice though, which could be an issue depending on volume. It's not a small amount of water, even in later summer.
Almost 12 years later and I still get excited thinking about this route; having gazed up at it, studied it in photos, and dreamed about what it might be like in those upper basins for years. getting our asses handed to us the first try. Getting more and more hopeful as each successive obstacle was passed on the second try. So, so many rappels and so much downclimbing in the dark down the east ridge after getting the to summit. Shivering with one sleeping bag and a space blanket just below the CJ Col after 24 hours on the move, wondering if the predicted rain was going to soak us, and the glorious acres of blueberries we found for breakfast the next morning. There is an experience doing a new route that is entirely unlike repeating; no tat, no cairns, never looking at a route description or trying to figure out if I'm 'going the right way'. Look up, choose the way that looks like it goes, then go find out if it really does. Beautiful simplicity and true adventure.
