Does anyone know if you can take the ridge below Mt. Mallory to Rosco Peak and Lone Pine Peak? I've seen a video of a Sierra Challenge group taking the chute from Grass Lake to Rosco Peak (same chute used to get to Lone Pine Peak), but I haven't found any trip reports of accessing Rosco from the west. I looked on Google Earth but the images get too pixelated when I zoom in and I can't get a good visual of the terrain. Thanks.
