Two men in their 20's are dead after an SUV plunged down a cliff in Mission late Sunday afternoon.

It happened just after 5 p.m. as they were driving along the Norrish Creek Forest Service Road north of the Lougheed Highway.

It's not clear what led to the crash, but they dropped about 150 metres down an embankment.

Two friends in a car behind them phoned 911.

Crews expect to recover the bodies on Monday.
