I've had several off line discussions with a few people about the recent collapse of part of the restriction (chimney) towards the back of the cavern at JB. As I understand it, the fallen rocks from the ceiling made passing in backmount difficult.
Has the possibility of such a collapse altered your approach to cave diving? If so, in what way? Considerations for going to sidemount? Notification of surface support of your dive plan and estimated time of return? More conservative gas rules to allow more time to figure alternatives? This is too dangerous and you're not gonna do it anymore? Something else?
