Ice Crystals in Colorado
July 20, 2007
These peculiar needle ice crystals were observed on April 7, 2007 in Colorado Springs, Colorado. They're approximately 3.75 - 5.0 cm in length (1.5 - 2.0 in.) and formed following a freezing fog. When the air is saturated and temperatures are below 0 degrees Celsius (32 F), trees and other objects exposed to the elements can quickly become coated with ice (rime ice).
