FATMAP difficulty grade
Of the three prominent couloirs on Les Rossetts, the first entry is the longest and the most technical.
It has a very narrow entrance, but once into the couloir it opens up the most and really is not even a couloir at all once you are 3 or 4 turns in.
In order to access the line, you need to be comfortable being over and under some heavy exposure.
There is nothing really difficult about the ski, unless you are dropping in early in the day after it has been warm the day before.
Then this line can be very sun crusted and icy due to the Southern exposure of the couloir itself.
