Went back several times to try and clear enough trash/debris/trees from the entrance to make penetration possible. Going downstream is now possible (very very tight). I made it to a permanent line past the first restriction. The line now goes straight into a pile of sand several feet tall. In what can only be described as shimmying over the sand pile, I got to what I think was the entrance to Lee's loop, then called the dive. Overall 0/10, so many glass shards in the first restriction, impossible to not crater the vis immediately. |

Lawn mower is tangled around primary line at around 30ft. Entrance to upstream/downstream was completely clogged with major trees/debris. Attempted downstream entry but aborted, without clearing no mount may be possible (side mount was not). |

How is this site presently (legally) accessed? I see a chainlink fenceand signs prohibiting access along Kelly Park Rd. and cannot identify any other access points. Please help, thanks! |

I also contacted the city years ago and had no response. I’m happy to help with the lawnmower and any efforts to get the hole cleaned up AND recognized for what it is. Please contact me I’m available this weekend! Let’s get this mower out at least. Would happily act as a support diver for any efforts/exploration as well. Josh.leavell@gmail.com |

Not Good. Major dead oak trees have fallen in. |
I received some complaints about trespassing and illegal activity on the City's property just north of Bluegrass Estates. There has been some spill over effect on BGE. As you probably know, there is a famous sinkhole called the Blue Sink on the city's property. I'm currently soliciting the City of Apopka to properly maintain the Blue Sink area including stopping trespassers. The city expects us to maintain our property, so I expect the city to do the same for city property.
The Blue Sink area has been neglected by the city for the last 21 years. The Cambrian Foundation did a major clean up back in 2003. I contacted Cambrian Foundation about the Blue Sink and they responded back saying they would like to be involved in the Blue Sink clean up again. |

Visited in 2019 to check if reports of being filled in were true, found nothing but a great depression at the GPS marker that looked like it could have been a filled-in Apopka Blue. Returned today after the last post saying it was not filled in, all I will say is that it is indeed NOT filled in, the GPS marker is incorrect. Extreme thunderstorm prevented any recon but I could see beautiful blue water going under the large limestone overhang.

Both the upstream and downstream sections are filled in with debris and sand. Sidemount might be possible downstream, but still very tight. |
