I agree if you are flying low and slow my two options would not work but having no time to calculate radius of turn or estimate radius required before your escape I would hug the downwind side of the canyon and make sure speed would not put me into the other side using flaps if necessary to make the turn as tight as required and banking to what ever was required without stalling.
Of course you first climb to use the altitude to use lift to turn,not maintain altitude and get to what ever speed is required to do your 180.
