North Iceland Lenticular Stack
From amidst a melange of multilayered clouds, a fine little stack of altocumulus lenticularis peeked to reveal a standing wave. Although altitudes aren’t too high in Iceland—mostly under 5,000 feet except for the very highest peaks—the high latitude ensures strong middle-level winds for much of the year that are suitable for generating waves that create such formations. Nine days prior, we were observing lenticulars on the opposite side of the island.
