No, that isn't correct either. depth hasn't significantly changed. The silty area without rocks that was near the 25' platform anchor is actually deeper.The report Capt'n Dave shared says the debris field is 35 feet deep. That's nearly half the depth at Blue Hole. Is it really that much?
The impact blew a bunch of silt out of that area, and I'm 99% certain that the old silty area is now deeper.
There's also a rock that fell opposite the debris field (see below) and when we were down there last time I thought that "the crack" was bigger and may have had more flow. That's pretty subjective and a guess, but my buddy thought the same thing. I've attached a couple of sketches for reference, apologies in advance for the (lack of) quality of the artwork.
