Do the swirls of snow on the runway indicate the a/c made a 180 for back track? If so, and the taxiway is to right, on the photo, the curious thought is how they ended up at 90 degrees to the runway BEFORE the runoff. The centre 30m of the runway looks clean.
But the tracks from the runway through the snow appear to be just less than 90 showing the a/c was turning left off the runway not right. In that case it is PAST the turnoff.
I apologise if I've missed a previous full description of the landing roll & turnoff.
