Our February Natural Mystery was a challenging track indeed. We received many excellent guesses, some with detailed explanations of the reasoning behind them. A few people got very close, but no one sent in a correct ID for both the species and the foot. What made this so tricky? Although the print was clear, it has a slightly uncommon form for the species and a very unusual size! The beast that made these tracks has been frequenting my yard lately and is by far the largest of this species I have ever seen. While identifying the single print in isolation was an extremely challenging task, I suspect that most of you will instantly recognize the track pattern.
