Journeys to the Ends of the Earth was a 1999 television series produced by the Australian Discovery Channel. It was the most expensive adventure travel series ever commissioned in Australia.
One of the early episodes was Ethiopia: Keepers Of The Lost Ark
"David Adams makes the pilgrimage from Lalibela to Gondar in the northern wilds of Ethiopia, and paddles by papyrus kayak across lake Tana. His quest: to find the Ark of the Covenant." (50 mins)
A bit of an odd programme, with quite a few factual errors, but still an interesting watch.
