When I first came here (about 8 years ago) there were still wooden planks on this catwalk. A sign said to keep out of the cave, so I did, but it would have been easily accessible. Now the planks are all rotted and getting into the cave would be a bit of a challenge. In addition to that, I have heard from several folks that organic decomposition inside the cave produces a fairly hefty concentration of gases such as methane. The only people I know who ever did penetrate into it did indeed get ill while they were there, which leads me to believe that the rumors of methane (or some other gas from organic decomposition) are true.
