Aerial photographs taken midway through the melt season of 1999

Aerial photos were taken during the melt season along four lines on two different 
days showing partial snow cover on the ground.  The photos were combined and justified 
into these seven images. Center lines of the photo runs are plotted on the location 
U2 photo. The remaining snow  represents places where the snow was originally deeper 
or drifted allowing analysis of the depth distribution through the use of a melt model.
