The story that the Ark is in Ethiopia may well be true. I posted an earlier article here from Crisis Magazine, which I think is much more convincing than this article. The Crisis reporter ended up at the same small church with the iron fence mentioned here.

I recommend this earlier article in Crisis. Fewer pictures than National Geographic, but maybe more substance.
I think its there.
Thanks for the link.
