Members of the Xeni Gwet’in First Nation were on the yearly wagon trip to mark the start of the Williams Lake Stampede when one stage coach went into a a ravine near Farwell Canyon Tuesday.
RCMP say six people were sent down the 40-foot slope, but all of the occupants were conscious when emergency crews arrived.
First responders had to make use of ropes and a winch to bring the injured to the road.
Four people suffered non life-threatening injuries while two were able to walk up the slope. One of the injured was admitted to hospital and is listed in serious condition. One of the horses also had to be put down.
RCMP say the washout along Highway 20 and the necessary detour also complicated what was a very complex rescue.
