Dr Shoch has shown that the weathering in the pit created when it was originally carved out of the bedrock is water weathering, so the pit has to be at lest as old as the end of the last Ice Age, ~10,000 years ago. west is convinced it was originally carved as the head of a lion and positioned to be gazing at the constellation of Leo rising on the horizon, which would mean dating by precessional changes. I am guessing it is two cycles back (~30+ thousand years ago).
Would the constellation Leo have been called ‘Leo’ by ancient Egyptians?...................Seems to me it is a Greek/Roman name from their mythology..................
