Plate 13
View looking south-southeast from about 9000 m (30,000 ft) along the Owen's Valley,
California, showing a roll cloud developing in the lee of the Sierra Nevada mountains. The lee-wave
crest is marked by the cloud layer, and the vertical turbulence is causing dust to rise high into the air
(W = Mount Whitney, 4418 m (14,495 ft); I = Independence) (
