Rime Ice (Pogonip) on Trees
March 23, 2005
The above winter wonderland doesn't owe its captivating looks to a recent snowfall -- there's no snow on any of the these trees. Dense, freezing fog occurred all day and night for almost an entire week (beginning January 17, 2005) here in Spanish Springs, Nevada. The freezing fog, called "pagonip" or "pogonip" by the Shoshone, which translates to "white death," readily accumulated on trees and most other exposed surfaces. Each day this veneer of rime ice was heavier. Temperatures were mostly in the 20s, and ice was everywhere. See the Earth Science Picture of the Day for January 4, 2005.
