WEST GLACIER - Two scientists from the United Nations are scheduled to visit Glacier National Park this week.

The delegates are looking at the potential impacts of coal mining and natural gas development across the Canadian border in British Columbia.

They are expected to tour the area for three days with scientists from Glacier National Park and the Flathead Lake Biological Station and then spend the rest of the week meeting with Canadian officials.

The concerns revolve around possible development on the Canadian side of the Flathead Valley, which spans the province's border with Montana. Opponents say they fear harm to water in the transboundary Flathead River system, but supporters say there would be safeguards.
