Cave Diving is the most dangerous type of diving there is. Meet a team of researchers who take the risk to explore parts of an Oregon cave that have never been seen before. The cave is a restricted site located in the lava lands near the Idaho border and is believed to be the only divable freshwater cave in the Pacific Northwest. The divers use kayaks, flashlights, and scuba gear to explore the thermally heated lava cave.
