Hello playmates.
What I'm attempting to do is reverse engineer some basic Megalithic Astro-Geometry. The original Megalithic Astro-Geometry Initiates (let call them MAGI) understood triangular coordinates. Just as the original Ordnance Survey used triangulation to map the whole of the UK, I am hypothesising that the MAGI would use the same to establish some base stations for astronomy. The base stations do have to be far enough apart to maximise (for example) the difference in the maximum height of ascension of any astronomical object.
As we are all Sleep Walkers, stumbling in the dark, fumbling to understand what's gone before, I'm trying to take a systemic approach, and run the number down.
e.g.
Your mission (should you decide to accept it) is to scour the globe for seriously suggestive sites that have the same latitudes.
