This seems a bit weird, but I looked up "Expedition Everest" in Google, and found a French-text website, apparently describing the attraction, but including photos of what looks like concept models that I've never seen before, with Disney imagineers that I recognize!! Links are below:
model with working imagineers
smaller model from a better viewpoint than above model
smaller model from different angle
very cool concept art of the mountain as seen from the main Asia bridge
finally CLICK HERE for the main "Expedition Everest" page, with links to the above concept art and model photos ON THE RIGHT HAND SIDE
