This sounds great, but I haven't seen the series advertised on our local TV programming. Doesn't surprise me, free-to-air is appalling now cable/satellite has taken over! Any one in Oz seen the show?
A couple of comments, just from what people have said in this thread, many of the early explorers here went through hell to get where and as far as they did. One guy called Carnegie details some horrendous stuff in his journal. To find water he often followed certain types of birds, grain feeding finches for instance, but when that failed he captured Aboriginals. Tied them up, fed them salty beef until they were mad with thirst then released them and followed to secret waterholes. Not very PC!! Another book worth reading is botanist Carron's journal, who went with Kennedy on his last (ie.fatal) expedition.
In the area I grew up, in the wheatbelt of Western Australia, there were gnamma holes. Naturally occurring depressions or wells in rock outcrops, that were covered with a stone lid by Aboriginals to hide them, prevent evaporation and to keep game from falling in. We never drank from them, but knew where a few were and that they held water. If someone came and removed the lid there often were dead roos inside.
In high school we learned survival stuff about water mostly, making solar stills, using roots to drain, or where to dig. Stay with vehicle in the bush etc, not much about cold and shelter like UK, Europe and US.
Anyway this programme sounds worth chasing up, as do enjoy a bit of history too.
Cheers,
