We basically followed Smoot's "Climbing Washington's Mountains" route. However, we worked toward the north side of the West ridge and traversed the permanent snow field to avoid the 3rd class scrambling that Smoot mentions, making this a straight forward 2nd class route.
Route Climbed: Persis to Index Date Climbed: Aug. 6, '05
It was a long day. Really liked the tarns along the way. Just a bit of route finding and veg belays. The gully taking you through to Anderson Pass is obvious. That was a question I first had. No problem.
Route Climbed: West Route (Mt. Persis - Mt. Index Traverse) Date Climbed: October 20, 2001
Climbed the West route along the ridge from Mt. Persis to the summit of Mt. Index. Descended the East Route to Lake Serene which required 1 short rappel and a lot of "brush belays" to descend from the ridge to the boulder field above the Lake.
