Wonder what kind of light they used. Wouldn't want to build a fire.

It looks like the south end of the Cheese Caves to me. Here's a picture taken from the area that I'm thinking...camera is pointing south.

Probably magnesium ribbon or powder. Set up the camera on a tripod, open the shutter, go around bend in tunnel,ignite flash, return to camera, close shutter.
A candle or three, or even lanterns, behind camera and near photo-flash location, would provide enough illumination to not be working in the dark, while not adversely affecting the desired image - so long as one didn't loiter in front of the camera.
