Heather Mountain, near the East Gate of Glacier National Park, is once again shedding rock, mud and trees.
So far this year, the long, slow slide, which began on May 21, has only caused limited periodic delays of up to 20 minutes, according to a statement from Parks Canada’s Partnering and Engagement Officer Tania Peterson.
The mountain began shedding its north face at this same time of year back in 2007. At that time the mud closed the TCH for a number of days as Parks Canada staff worked to clear it.
In 2009 Parks Canada built a catchment basin to help reduce the risk of mudslides hitting the TCH. The catchment basin is proving effective in collecting mudslide debris while Parks Canada Highway Service Centre crews are busy working around the clock using back hoes and front loaders to clear out the basin and ensure it can continue to collect more debris.
However, due to the unpredictable nature of the mud flow, longer disruptions or closures are possible.
