Mount Index consists of three summits: the South, Middle and North, in descending order of height and shown left to right in this winter picture. Traversing the Peaks from North to South (right to left in the picture) is referred to as the Index Traverse. The South Peak is a moderate scramble, so is frequently done by ambitious hikers. The North Peak is the most prominent feature when viewed from the highway and is a challenging climb by itself. To do the Traverse, rappel into the notch toward the Middle Peak and climb from there. From the Middle Peak descend toward the South Peak, climb the South Peak and descend via the hiker's route.
