Watch the third episode of Mummies Unwrapped. I waited so long to start watching it, that the first two episodes went from DVR to VOD. VOD and you can't skip commercials.
Should probably watch the rest of them before it goes to VOD.
Most of the tombs were looted. They need to find a relic to know where they came from. They found a tomb in a cave, in a hard to reach area, they had to descend a waterfall to get to it. No relics, not looted, just water probably washed stuff away.
I heard about that show on Expedition Unknown.
