Two heavy rainstorms caused flooding and landslides in the upper valley last week, damaging infrastructure and leaving two residents temporarily trapped in their vehicle.

The landslide, estimated to be 300 feet wide, has completely cut off the community of Lowell Point. Lowell Point Road is the only land access between Lowell Point and the City of Seward. As a result the City of Seward cannot access critical wastewater facilities.

Robert Service Way and the Millennium Trail and the Airport Trail near downtown Whitehorse are temporarily closed due to an apparent landslide on the escarpment around 3:00 p.m. on Saturday.

All 275 people were expected to be rescued by the end of Monday, said B.C. Public Safety Minister Mike Farnworth, adding that there had been no reported fatalities. The Agassiz fire department was credited with saving 12 people Sunday night in “treacherous conditions,” as their vehicles filled with debris and water.

Of the 140 unstable slopes along the 92-mile park road, Pretty Rocks has the most potential to disrupt traffic.

Heavy rains in Yukon and northern B.C. take a toll as overflowing creeks bring silt and debris down onto roads.

The highway closed after rocks covered the northbound lane at mile 111, near McHugh Creek. A second rock slide was reported near mile 106.5.
