Bears and a potential mudslide has led Environment Yukon to shut down two territorial campgrounds.

The Congdon Creek campsite near Destruction Bay was shut down after four grizzly bears were seen in the area eating soap berries, Environment spokesman Dennis Senger said this morning.

The territory isn't aware of anyone being confronted by the bears, which included a a sow with two cubs and another grizzly on its own.

There was one camper at the Congdon Creek site who was advised to leave, while four campers at the Kusawa Campground were advised to move on to the Takhini River campground above the Kusawa Lake campground.

The Kusawa campground is off the Alaska Highway south of Whitehorse.

A weather station installed four kilometres northwest of campground earlier this year raised concerns for staff monitoring the station in Whitehorse. The Yukon Geological Survey had recommended the station be installed.

The station showed a 48 mm rainfall in 28 hours and excessive moisture in the soil. With those conditions, Yukon Parks opted to use the precaution of closing the campsite in case of a mudslide.

The nearby Takhini River campground has remained open because it's not on the lower ground that Kusawa is.

Barricades as well as signs stating the campgrounds are closed have been used at the sites.

It's unknown when either will reopen.

'They're going to monitor (the situation),' Senger said.

While weather conditions at Kusawa can be viewed from Whitehorse, parks staff were planning to go to Congdon Creek Monday to reassess the situation and see if the bears have moved on.
