Aerial photographs of the ice fields atop Kilimanjaro on February 16, 2000 (A) and October 15, 2007 (B). Note that two photos are required to cover the area in 2007 as emphasized by the white gap. Both images come from unrectified photos in which tilt and relief displacements have not been removed, thus possibly giving false impressions of the relative sizes of features. Both glaciers and snow cover appear in these images and cannot be distinguished at this reduced scale (≈1:100,000).
