Stunning.

Lenticular and wave clouds are cool, but they don’t hold a candle to the undulatus asperatus clouds. Not new, but new to science, its Latin name means “undulating wave”. it’s like staring up from under the sea, or from beneath an undulating ice formation, except we are seeing a cloud rather than a solid or liquid.

They look ominous, but are rarely stormy. Why they form and what their pattern means? I haven’t been able to find anything. Can you?

Other Worlds on Earth by Geo:

“This photo was taken near the top of the Ka Lu’u o ka’ O’o hike which descends 1400 feet into the Haleakala Crater. The elevation here is about 9,400 feet, not far below the peak at 10,023 feet. As you hike into the crater, the views are similar to the images of Mars returned by the NASA rover.

Haleakala means House of the Sun. It is the tallest mountain on earth that is not part of a range. The last eruption was in 1790. Polynesian legends say that Maui leapt from his hiding place here and lassoed the sun, Kala, which he beat for racing across the sky so quickly each day and not providing the people with enough light. Maui broke some of Kala’s strongest legs leaving only his weakest ones with which to crawl across the sky, thus providing the people more daylight.”
