Presidential Boobs

at

There’ve been a few (but none quite like the outgoing one).

Behold: a spectacular display of mammatus (breast-like) clouds over Mount Rushmore last September. To wit:

Unlike normal flat-bottomed clouds which form when moist and calm air plateaus rise and cool, bumpy mammatus clouds form as icy and turbulent air pockets sink and heat up. Such turbulent air is frequently accompanied by a thunderstorm. Each mammatus lobe spans about one kilometre. The greater mountain is known to native Lakota Sioux as Six Grandfathers, deities responsible for the directions north, south, east, west, up, and down.

    Mount Rushmore looked great in the spectacular finale of Hitchcock’s suspense film North by Northwest. Eva Marie Saint outstarred Cary Grant and should have won an Oscar that year.
