A giant open pit coal mine is proposed in British Columbia just north of Montana close to Glacier National Park. I have linked to articles about this proposal for years, but now the reality of the mine is much more solid. The coal would be shipped to China.
There are already similiar mines to the north in the Elk River Basin (a stream that does not drain directly into the United States).

I discovered there is a blog, written by folks who live near the North Fork of the Flathead River, that gives a lot of information about the “Cline Mine.” See North Fork Preservation Association blog.

Update. Jan. 20. Here is a photo of what to expect. It is of Coal Mountain in the Flathead Range of the Rockies (British Columbia). This longstanding coal mine is 10-15 miles north of the proposed Cline Mine. It drains into a different river basin.
