![]() Trident Peaks Aerial view southwestward of the four eroded peaks of Trident: East Trident (6010 ft elevation) with ice-filled bowl at the base of sheer north-facing scarp (left center). Smaller dark peak to its right is also an eroded remnant of the East Trident edifice. Trident I (6115 ft elevation) on central skyline is the highest summit. West Trident (5605 ft elevation) is younger than the other two and much less eroded (far right). Youngest of all, Southwest Trident, is out-of-sight behind West Trident and Trident I. Shadowed knob, lower left, is non-volcanic basement. Lower snow-covered slopes of Mount Mageik are in the uppermost right. Light-tan colored 1912 pumice and ash mantles all but the steepest slopes, even the Knife Creek Glaciers, rough terrain in the foreground. Photo by Judy Fierstein; August, 1999. |
