Dr. Derek Ford, who was a colleague of mine at McMaster University, and I located a karst area just above the city of Hamilton. It's now part of one of the conservation areas. Dr. Ford has clearly identified the radiation effect, if you want to call it that, of the karst.
Your best intention is that you drop the water in here and you would suspect it might come out there, but that's not the case. So I think the rationale that you're outlining, not only the unique feature of a karst.... There are not a lot of them around. You have to have the right combination of sedimentation and rock values and things like that. When you identify a karst and there's some way you can incorporate it, in my opinion, it will make another unique feature of Nahanni. Like probably all of my colleagues here, I've heard about it and I've seen the pictures, but the characteristics are just so much sense.
With regard to watersheds, I'm a firm believer that what you put in upstream has an adverse effect not only along the stream, but at the bottom end. I think Montana and even British Columbia and those particular areas have indicated the potentially detrimental impact it could be outside of the borders, which would affect everything inside and downstream.
I probably have a minute if somebody would like to comment on that. I can always come back to that question later on.
