Thanks for the reply and the link Sheridan..
I now 90% convinced it is from a wolf. I very truely hope that is not the case. But the info on that link makes it look like a sure thing. I tried to take a picture of the track but my camera skills are seriously lacking. I realise this picture is not clear. The track is in mud that has frozen so there could be some shrinkage. Any ways here is the best I could do yesterday.
