Entry into prohibited zone forces closure of backcountry area around Rogers Pass

A portion of Glacier National Park near Rogers Pass has been closed to backcountry excursions after several people entered a prohibited area where regular avalanche control is conducted using artillery fired from the highway.

Parks Canada staff noticed tracks leading from an area that requires a permit to enterand going into the adjacent Macdonald West Winter Prohibited Area.

"When we saw those tracks entering, one of the problems is that it tends to attract other skiers into that area as well," said Danyelle Magnan, an avalanche operations officer in Glacier.

"And it's really important to us that we have compliance with our winter permit system that's essential. So as a result, we close the adjacent area until we have enough snow to cover those tracks and it doesn't keep drawing people into the prohibited area."

Not only are explosives fired into the prohibited area in order to protect the Trans-Canada Highway from avalanches, staff from Parks Canada also use the terrain to examine the snowpack and develop avalanche forecasts.

The military fires explosives into the mountains of Rogers Pass as part of an ongoing program to fight avalanches.

The people who entered the prohibited area had already left by the time their tracks were discovered, so Magnancouldn't say whether it was on purpose or accidental.

"We have excellent compliance, it's why our winter permit system works is because overall we have wonderful compliance," she said.

"Our visitors respect the rules and they appreciate that the system is in place for their safety and to enable them access into these areas."

Those who enter prohibited areas may face a maximum fine of $25,000.

The area will remain closed until further notice.
