The bay was mapped a number of years ago with sonar (think that was it), but not very well. We were intrigued by a few things. Upon exploration, those things ended up being nothing, but we found these large rocks laid out in a pattern and pointing somewhere particular. They had not shown up on the maps because the sonar skipped this section, and no one had ever dove in this area.
For the coconut fiber, the boobytrap was tripped a loooong time ago and this stuff was well known. Some folks had already found coconut fiber decades before (which aided the trap), and a semi-sane man took a few hours to help re-locate one of the "fingers" of the trap that had the fibers. Long story short, we found more of that fiber which was placed there when the trap was built.
Was exciting to be there in both of those!
