I too read an article about acid rain and the Adironacks a few years
ago. The thesis was this: (1) Before logging started, there was acidic
runoff due to decay, as Bill states. (2) Logging or clear-cutting produced
enough alkaline material to neutralize much of the acid. So, there
are pictures of Teddy Roosevelt fishing in the Adirondacks. (3) We
could today easily neutralize the Adirondacks acid by liming, spending
perhaps $500,000 per year. In other words, mammoth projects to counteract
acid rain effects are not necessary.
Like Bill, I cannot remember exactly where I read the article. But
I think it was in *Policy Review* three or four years ago.
