A letter from the Photographer

Dear Captain,
You will find enclosed 6 photographs I have taken of the crystal and other wonders in the cavern. Due to the reflective and refractive nature of the crystal, it was very challenging to take photographs and have them be decipherable as anything more than light. However between diligent photography, some clever developing, and shear number of photographs I have managed to produce the enclosed photos. The first is a sample of the crystal I took back with me to HQ so I could photograph it in better lighting, curiously I found an ant enclosed in one of the crystals. The second photograph I took was of a fish I managed to catch which I also took with me back to HQ. The third is of a fantastic specimen of crystal no less than 8 feet tall, the nature of the conditions caused the crystalline structure to be particularly apparent. The fourth picture is of the gorgon inscription over the inlet tunnel. The fifth picture Is of a particularly plain crystal that with proper lighting I was able to discern something inside, I have provided a second copy of the fifth picture that I have done some retouching to to make what I believe I saw more apparent.
I hope these pictures find you in good health and I hope that I can do more work for you in the future.

Sincerely, George H. Dennison, Company photographer

P.S. If you would put in a good word for me with the Colonel I am hoping to convince him to requisition a more modern camera for me.
