Video: An Expedition to One of the Deepest Caves on Earth

Think cave diving simply involves showing up at the site, putting on your gear, and dropping in? Think again. In this video, we get a glimpse of the logistics involved in simply reaching the Dark Star cave system in Uzbekistan, which is believed to be one of the deepest on the planet. The team of explorers who recently went to the cave spent hours on a bus just to reach their starting point. They then trekked for two days to get to base camp, located above 12,000 feet (3657 meters). The cave itself has seven known entrances, each of which requires rock climbing skills to reach. In other words, this is no walk in the park. Check it out below.
