RCMP say a pickup truck struck an elk as it crossed Highway 3 near Crowsnest Pass, Alta., on Wednesday night.
The vehicle was damaged but the driver was able to safely park on the side of the highway and activate their emergency lights. The driver was not injured.
Shortly after a woman in a second eastbound vehicle swerved to avoid another elk but lost control.
The vehicle, which had two occupants, turned sideways and skidded into the parked truck.
The woman was pronounced dead at the scene. EMS also transported the 35-year-old male passenger from Fernie to hospital in the Crownest Pass.
RCMP says road conditions, which were partially snow and frost-covered, are believed to have contributed to the accident but an investigation is still underway.
