Crowsnest Pass RCMP, fire and EMS officials were called to the scene of a single quad rollover in a forested area just north of Coleman, Alta., at 9:30 Friday night.

The female passenger sustained minor injuries while the male driver died as a result of the accident.
The identities of the two will not be released until police have notified the next of kin.
