Taken on a trip to Haggard Cave, several cavers from Georgia Tech make thier way down the breakdown slope into the room I named for a white stain on a slab in the center of the room resembling a woman in a long dress with windswept hair.
This shot was used on the cover of the NSS news, a monthly magazine of the National Speleological Society, dedicated to caving and all aspects of it. http://www.caves.org/
That was handheld, single flash, a Honeywell Strobonar 700. Above the cavers is a horizonal tube with the bottom open to the room, the hole just behind them is the access. I was on the breakdown across the room from them where the passage continues taking a rest break.
