I'm very confused on a 'discovery' i found somewhere in a desert. It's a pyramid i found, but i'm confused if i discovered it, or i'm unaware that it has already been discovered. The image is here. The part that confuses me is that I have BD Armory, Kerbal Konstructs and Kerbinside. When I check the map I see no symbol on the location that I am on. Is this an undiscovered easter egg or something? If anyone wants the coordinates, they're 10° 49' 0" N, 127° 24' 16".
