Here’s another willardi from 2011, and to be honest I don’t remember anything about this one. I was fortunate that year and saw a bunch of them, and now I’m all mixed up. SO, with that admission: here’s a good example of that cool ridge that sets these guys apart from other US rattlesnakes. When in a spot between bunchgrass, even very experienced herpers can step right over one. I am sure I have done my share of just that.
