The ride down is generally gentle, although there are several alternate routes that have differing degrees of steepness in certain sections. But ultimately, you start and end at the same place so no matter what route you take, it all has the same average angle of descent. You are on glacier for 90% of the ride down and will encounter crevasses and bare ice. There are also a few rocky outcrops. There is a steep roll towards the bottom of the line, just as you leave the glacier and before the flat run-out to the base station of Le Tour ski resort. Some lines through this roll over are easy, some are short and steep. Take your pick.
Via Bec Rouge Superior and then Bec Rouge Inferior: An alternate descent is to leave the lunch point by the normal route, but staying skiers left in the very big wide open 25 degree slope that can be full of soft snow or full of sastrugi. Part way down we headed further left and belayed each other down a 10m rocky face whilst still riding our boards. There was enough snow to avoid the rock, but a clumsy fall put you directly onto stone flowed by a short tumble over more rock. No big deal, but if you don't feel confident then set up a boot axe belay or something like that. When you unclip from the rope you are standing at the top of a very tempting looking northerly 35-40 degree bowl with a rounded rocky head wall at the top and the snow when I passed through was cold and shadowed. I have never dropped in here. I bet it would be good, but also looks just perfect for avalanches. We traversed around the top of the bowl further to skiers left, dropping down hill a bit as travelled a few hundred meters. From here we put in a short and steep boot pack up a ridge and yet again to skiers left. This leads to the entry point of the much less travelled descent route. The day we rode it was great with a foot of soft snow (not really powder). There are several sections that range from good bowl riding to undulating terrain. There are several alternate lines, some offering pretty good slide avoidance. Some also lead to flat dull sections.
