Grand Teton Panaroma and Crepuscular Rays
December 14, 2006
The photo above showing the sharp silhouette of the Grand Teton Mountain Range in Wyoming was taken at sunrise on September 28, 2006. The photographer is in Idaho, on the west side of the "Tetons," looking east. The sunbeams and dark lanes fanning out from the ridge-line are crepuscular rays. The highest peaks of the "Tetons" are effectively blocking the dawn's early light. This impressive range, featuring a dozen summits climbing to 12,000 feet (3,658 m) or higher, rises abruptly from the valley floor, about 1 mile (1.6 km) below the ridge-line.
