Finally found a sinking location - opinions and advice?
Posted: Sat Dec 25, 2010 7:09 am
Okay, some of you might remember my occasional posts about trying to find a location for sinking near Sydney, Australia. Tonight, I finally found one that I could actually confirm. Last year, my research identified Thirlmere Lakes National Park as being a prime candidate location, and it looked okay on Google Maps, but I ran out of time to check it out in person. News articles have appeared in the last few months which confirm that the location has exactly what I'm after - deep mud. Nearby mining seems to have fractured the underground water table, causing the lakes to drain and expose the underlying mud. They've even gone so far as to post warning signs about the mud.

Given this, I'm planning a trip out to the site as soon as I can manage it, but I wanted to get people's opinions and advice on this first. I also had some specific questions:
Anything else people can think of would be greatly appreciated.

Given this, I'm planning a trip out to the site as soon as I can manage it, but I wanted to get people's opinions and advice on this first. I also had some specific questions:
- Given that this drainage has been caused by mining, is there any risk of ground subsidence? Could this increase the danger of the situation?
- Do the warning signs indicate an actual danger, or just a perceived, hypothetical danger as imagined by the Park Rangers?
- Should I go out there alone or with someone else?
- What are the critical things I need to remember when sinking and trying to get back out?
- Is it worth running the Park Rangers to try and do this?
Anything else people can think of would be greatly appreciated.
