I found this Black-Tailed Rattlesnake, Crotalus molossus, while hiking along a streambed with my sister in August of 2009. It was the first she had seen, unless you count the unfortunate roadkill we found near Douglass the night before. I love this species; it completely made our afternoon to find this guy.
