Note From SS Archaeologist Randolph 2

March 17
My God, I can't believe what I have just seen.
We cleared the way into the inner vault. One of the men died in the explosion. While the others took care of the body, I could not resist opening the gate into the vault, despite what Helga said. I put a cloth over my mouth because of the strange green colored gas, but it got into my nose and left a burning sensation.
Entering the inner vault, I was struck with an overwhelming sense of awe. Such an impressive feat, to build such a vast chamber this deep into the mountain. There seems to be no end to it. There must be treasures hidden here. Magnificent treasures of real historical value. Also, I observed the unidentifiable gas released from the cracks in the ground caused by the earthquake. 
In front of the entrance, there is a mechanism of sorts. Symbols on it, the same as on the map we retrieved from Helga's patient. Maybe it controls the aperture at the bottom of the pit. Helga has the map, so I cannot test this hypothesis yet. Something seems to be locked away there, underneath the earth.
Hoping Helga will get here soon so we can study this further.
