This photo pairs shows two views of Igloo Mountain looking to the east from above the Tattler Creek area. From the altitude of this photo, it is difficult to detect many changes that occurred over the nearly three decades that separate the two images, especially with the different character of the lighting in the two images. This brings up an important point about using repeat photos - changes in the direction or intensity of the light can exaggerate or hide differences on the ground, and it is very important to look very closely when examining the repeated images!
