A better look over the half-door as we move closer we can now see its workings, support and trigger exposed from a partial collapse. We can also see past the trap to the open cavity beyond. If you look closely at the upper area, the top rock is triangular and has an “eye” carved into the apex. Above this gable stone is a massive chimney of loose rubble and rock. The left edge of the gable stone rests precariously and under pressure against a round “roller” stone which is part of the trigger system. This rests on a “bridge” support stone that lays across the entrance at the midpoint. And this in turn rests on pillars. Any manipulation of any component breaks the integrity of the set and the roller will slip allowing the gable to drop and all the many hundreds of tons of material in the chimney to drop and fill this entire void. A master trap 300′ down through a labyrinth of faults and fissures… I could go no further at this point. Someday we will return with tech built for the job and see what lies beyond.
