  3. And you can actually see where the men were up there and they didn't, you know, they may have like four or five, even six inches between two stones.
  4. Upwelling is also influenced by factors such as the topography of the local ocean bottom and coastlines, the climate, and wind patterns.
  5. Radiocarbon technicians prefer to test wood and wood charcoal because their high molecular weight mitigates material loss during the rigorous pretreatments required for radiocarbon testing.

Akapana, ancient pyramid was built? True north and true south are found at the North Pole and the South Pole respectively, forming the axis that Earth rotates on. It is likely that, by the pyramid age, the Egyptians had been intensively exploiting wood for fuel for a long time.
