Well, you know somebody somewhere would like to sue someone else for not informing them about such dangers.
On a related note, I recently watched a YouTube video about some people who decided to build a very large (3 storey) 'cottage' in Glacier National Park some time ago. It seems that the local government didn't want to be involved with the permitting process, claiming that because it was inside the boundaries of the national park, it was a federal government matter. In the end these fools built this eyesore some 10 feet from the water's edge, but construction was stopped when someone finally got involved and made a complaint based on the potential for water pollution. If I remember right it was near Lake MacDonald.
As for the lack of qualified trades people, well nobody wants to get their hands dirty anymore, they all want to make hundreds of thousands of dollars sitting on their asses in a nice comfy office, or at home.
