|Silver Creek Cave is developed in a tight fold in massive chert within the Cambrian age Conasauga Formation. This is an unusual cave development. Upon closer inspection, I noticed remnant carbonate traces along the walls of the cave. Looks like the massive chert completely enclosed a carbonate core which solutioned away. The west wall is only four feet thick.|
I looked for this cave three previous times using location data from a 1970's Georgia Speleological Survey publication. Every time I found myself near this location but never looked closely because I saw no limestone exposed. The publication never said the cave was developed in chert.
This image was somewhat complicated. I had to deal with a very bright sky, which I mostly eliminated with framing. The overhang and cave were very dark. My camera was on a tripod, ISO 400, aperture f/7.1, and shutter speed 1/125 of a second. I had a Canon flash set to full power -1/3 on a sync cord to illuminate the overhang and entrance areas. I had one slaved Sunpak 383 set to full power in the cave to illuminate Brad and Caleb. It balanced well.
