Everybody else has already linked to this, but hey, bringing up the rear is my standard modus operandi: An interactive graphic of a trek to the top of Kilimanjaro. It does all sorts of jazzy Google Maps stuff and includes videos and audio tracks from Tom Bissell, who made it all the way up.
(This is local because everybody around here has either been up there or has it on their life list. Link via the excellent Adventure Blog, a Kili veteran.)
