Here's a short video of Brian Richardson (litehedded) and I on our setup dive from our last exploration of the downstream tunnel of Black Hole Swallet.
it's a very unique cave system in that it's a swirling vortex of a black siphon for most of the year. There is a crystal clear spring tunnel upstream of the sinkhole that helps to clear it out quickly once the creek stops flowing into it.
4000' laid and surveyed so far. Hopefully conditions will be favorable for further exploration in early 2015
