The images below were taken on a day when the windows in a leaky cabin had extensive crystallization 
on them (there are many days like that in the deep of winter), and the sun was just right for back-lighting.

These pictures immediately below sort of give a context of the source material for the main images further below, which were  basically substantially
zoomed images of these contextual images. The scenes were basically looking thru the ice covered windows, thru to trees and snow.
