This would make for an adventurous hike. An exhausting, but rewarding hike.

A mysterious glow on a subterranean lake. This image started by accident, with the camera under the landscape, the strange view was too compelling to ignore.

Wouldn't it be fun to have a basement room that looked like this? A great place for a pool party. Just don't fall in the big hole in the back yard while mowing the lawn.

This turned out to be much more difficult than I thought. I wanted it to be a view from inside an ant hill, looking down several tunnels at once. But since you can only point the camera one direction at a time I had to opt for a more cavernous approach.
