The summit of Little Brother offers a bird’s eye view of Collier Cone and Lava Flow with a spectacular vista of the High Cascades beyond. Take note of the breach in Collier Cone’s western flank, the source of the Collier Cone lavas; as well as the position of Collier Glacier’s Little Ice Age terminal moraine, some of its debris forming a veneer on Collier Cone’s southern rim.
