In reply to stu maci:
Usual consensus for a route like Lipton? M7, WI5-WI7 is quite some range...
As always, ice grading is extremely condition dependent.
If I understand it correctly the ascent was from 2010, same year as the american female guide. My wild guess would be that the route had a handful tops a dozen of repeats that season. Lipton was unusually hard that season.
On the other hand when the curtain is full and touches the ground, it goes at WI5 and could easily have a handful repeats over a weekend. Might even be queing!
In the context of women and hard iceclimbing I find that this is newsworthy. Probably theres dozens of east & central europeans and french women whos capable of doing it but who knows?
Its for sure more newsworthy than an 8c sport route done by men. Must be over a thousand male climbers who climbed 8c sport.
