High Sierra UFO

Check out this crazy cloud that went floating by when I was up at almost 11,000 ft in the sierras.  I've never seen anything like it.

It looked like 3 of 4 layered disks, but it also had these funky dark holes punched through it.  Very weird.

Anyone know what this type of cloud might be called?


  1. Hi Tim. We have these clouds a lot on the eastern slopes of the Sierras. They are called altocumulus lenticular, or wave clouds. Carolyn

  2. Carolyn - thanks! This gave me the info I needed to look these clouds up. Lots of good info and pics on google. Sounds like these are high altitude clouds that form near mountains. I never came across them before (even though I ski a lot). Who knew !
