People trying to travel west or south from Jasper are stuck between a rock slide and an avalanche.

A "controlled"avalanche swallowed a section of the Icefields Parkway on Thursday, shutting downHighway 93 North between the Trans-Canada Highway and Highway 11.

Parks Canadatriggered the snowfall to reduce avalancherisks near Lake Louise but brought down more snow than they had intended.

On Friday morning, a rock slide also cut off Highway 16 west of Jasper.

Crews were working to re-open both roads Friday night and updates are expected Saturday.

DarrylRopceanwas on his way to ValemountFriday when the rock slide blocked his way.

He described the scene in Jasper as chaotic, with a line of parked trucks and recreational vehicles snaking down Highway 16 near the town.

"Every hour that goes by, it gets busier and busier," he said.

"Anybody thinking of coming here if you're not going to stay in Jasper, if you have to leave south or west, you really are wasting your time."

Ropcean may have to spend the weekend in Jasper, he said.

The risk of further rock slides makes Highway 16 too dangerous for traffic, saidParks Canada spokesperson Joseph Zebrowski. He could not give an estimated re-opening time as of late Friday night.

"Our biggest concern is what's still up on the rock face," Zebrowski said.

"We really can't say what the risk might be but we are concerned enough of the risk of further slides that we want an expert to come in and do an assessment before we re-open the highway."

A geotechnician from Edmonton will inspect the rock face on Saturday to determine how it can be secured.
