In the image File:Mammothterracetrees.jpg it says that it was the calcium carbonate the cause of the death of these trees. I think a reference for that claim is needed. It is not so clear whether it was the calcium carbonate (I can see there is a lot of it) or much more toxic ones as sulfates and nitrates also present in thermal areas. If there is no so reference it is safer (according to neutrality) to just say that the high concentration of salts (in general) killed the trees, although it would remain questionable because it could have been high temperatures or who knows how many other phenomenons can kill a tree in such an unstable environment. franklin 01:50, 5 February 2010 (UTC)[reply]
By the way, it also says "calcium carbonate dissolved in hot spring water...".Calcium carbonate is not soluble in water! If it is dissolved it was provably calcium sulfate or maybe calcium chloride... and then it is more likely that it was the sulfate ions or cloride's the ones that killed the tree. In any case I find that claim very questionable so please provide references or change it. franklin 01:58, 5 February 2010 (UTC)[reply]
