Image of Crotalus oreganus helleri Meek 1905
Description:
"""This rattlesnake was on the Switzer Trail, a couple of hundred yards before the falls, in the Angeles Forest on April 14, 2014. He was close to the stream and would likely have taken a drink, but our presence changed his course and he took cover. We waited patiently, but he would not emerge for a photo of his head."" - Clare MK Observation and photos by Clare MK."
