Carlos Avery Wildlife Survey. I believe these are weasel tracks. The animal is moving left to right in each of the photos. It crossed the road beginning in a 2x2 bound, then transitioning into a classic bound. Trail width is 2" - 2 1/4", which suggests a small (female) long-tailed weasel.

Carlos Avery Wildlife Survey. Not sure about the species here. The size leads me to suspect snapping turtle, but there is lots of plasteron drag, which is unusual for snappers. Perhaps because the sand is so deep?

Carlos Avery Wildlife Survey. Another dug out snake nest. This time, there were two relatively intact eggs in the hole, in addition to one that had been consumed. This was in a different area from the other observations. See more discussion here:

Carlos Avery Wildlife Survey. A snake egg dug out by what appears to be a raccoon. My best guess is that these are (were) bullsnake eggs. Bullsnakes (our local gopher snake) are quite common in the area--and I found two trails that I believe are from bullsnakes in the immediate area. Bullsnake eggs are reported to be "up to 2 3/4" long." these appear about half that, but perhaps 2.75" is unusual? From my reading, snake eggs typically expand after being laid as they absorb water from their surroundings. I can't find much information about breeding, but Oldfield & Moriarty (1994) note that they usually excavate a nest under a rock or log--which is not the case here. They also report that bullsnakes lay there eggs in June--and these seem likely to have been freshly laid. I found more than a half-dozen of these small nests dug out, apparently by raccoons, in the immediate area. Whatever was laying them is very common (or at least prolific).

Carlos Avery Wildlife Survey. I believe this is a bullsnake trail. Bullsnake are common in the general area, and the habitat looks typical. Other snakes in the area include Hognose (eastern and western) and fox snake. Tkaczyk notes that hognose move with a short, wide lateral undulation not seen here. He has no information on fox snake movement, and there are no observations of fox snakes in this area.
