Last week I spent a few days at Lake Tahune, and noticed the mould on the interior wood cladding is pretty widespread. The wood itself is beginning to rot, and it smells dank. I doubt it's healthy. I've emailed Parks / Lyn Robinson, with the offer of participating in a cleaning session. But I think a more permanent solution would be ventilation under the floor and in the roof, and windows on the western side, and skylights.
Lake Vera's hut doesn't have any mould, and has a lot of sunlight pouring in, but it's also not clad in steel or sited at the higher altitude. It's also raised higher off the ground, with plenty of under-floor ventilation.
Here's a suggestion: if you're visiting, keep doors and all windows open during the day, to help to dry the place out.
Also, would anyone be interested in joining a cleaning party? It'd probably take an afternoon, with vinegar/alcohol, lots of clean cloths, scrubbing brushes, masks (to keep spores out) and gloves.
Anyone know how to get in touch with Terry Reid? He visits the place more often than anyone else, so he would probably be a good person to contact.
