  Gate of the Sun and Kalasasaya, Tiwanaku

  How did the Tiwanaku, working at nearly 3,850 metres without iron tools, carve the Gate of the Sun and its intricate Sun/Staff God frieze from a single ten-tonne block of andesite, and lay out the cardinal-aligned Kalasasaya so precisely that the equinox sun still rises through its eastern gateway?
