Poor thing dead in a tire track; which snake?
Sign only, print of a very wide bodied snake moving across the trail. The track has been tred on by hikers and bikers, so it is at least several hours old. The 3rd photo is of another, nearby, smaller snake track.
Better be careful where we’re walking, since the weather is heating up. I found this type of snake at someone’s front yard while walking. There are snakes that not only come out at yards (both front and back) of the neighborhood, but also at the parks, trails, and national Forests.
