I just about posted the 3D image instead of the link ... however, it is nearly 500kB, so I elected to let you click. HIGHLY RECOMMENDED!

I have, or rather, my daughter has, two pairs of 3D glasses. The image didn't work well with the first pair, but with the second it is tremendous! In 3D, you can't help but see that the three building thunderheads in the relative foreground (right, middle, left) are outside the anvil, and that the huge anvil is clearly and literally overshadowing the other clouds further than those building clouds. It's worth hunting up the 3D's if you have 'em. Both pictures are worth looking at even if you don't.

I wish they had given altitudes for these formations. The anvil is probably on the order of 45,000ft, but it could be somewhat lower or much higher than that.

Someone undoubtedly has a ping list appropriate to this “pretty weather picture” article...

That is one of the coolest things I have ever seen!!!

Thanks for the ping, but the last link doesn’t work.

I have no official list to ping but will select a few of my science oriented pals.

thanks for ping AFPhys! quite interesting
