A couple of weeks ago I made a loop from Easy Pass to Silent Lakes, then to Fisher Pass via the south slope of Arriva, then over into the basin below the Douglas Glacier, and from there down to the trail and back to Easy Pass. With a light pack and/or a little determination this is about three days. I took longer, and climbed Arriva, Fisher, and Logan as I passed. I used boots and axe in a couple of places, but the only place I put on crampons was on the Douglas Glacier, which is optional. The whole trip was never more technical than second class, with some bushwacking. I recommend it - it was a lot of fun.
