Occurrence Remarks: Beautiful C. lepidus klauberi found in a shady, moist, rocky canyon bottom. The snake didnt move as we observed and photographed it for about 10 minutes. When we started walking away the snake moved into a cavity in the rocks. This is by far the greenest klauberi Ive ever found and probably the second largest. Finding this was very unexpected because we werent even trying to herp that day, but extremely exciting to find my first klauberi in Mexico.; Coordinate Uncertainty in Meters: 29656.00000.

Occurrence Remarks: Appearance: This snake is approx. 2 feet long with a round head. The color of its body is light brown with dark brown banded stripes long its back. Like other rattlesnakes, this one also has a rattle at the end of the tail. Behavior: It tries to blend in with its environment first, but when the snake knows you see it, it will either start to rattle, continue to stay still, or try to escape from danger. Only when it feels that it is in danger will it strike.; Coordinate Uncertainty in Meters: 11.10000.

By the time we found this snake it was early afternoon and fairly hot. I spotted the snake in partial shade on a rock outcrop and let Brian get photos with his camera before the snake retreated into the rocks. I was able to get this very poor image of the snake once it was mostly hidden. The image shows the banding at least, as well as the very dark ground color which was the darkest Ive ever seen in this subspecies. It was a great day of herping and Im happy we found the target species!; Coordinate Uncertainty in Meters: 29093.00000.

When we walked up and noticed the snake I thought I could get a photo before it fled but it was too fast and retreated into a crack in the boulder while rattling.

Occurrence Remarks: C. l. klauberi observed in the Chiricahua Mountains around noon. I found the snake while exploring a small, wooded canyon, where I noticed it coiled on the rocks on a north-facing slope about 15 feet above the canyon bottom. I appoached the snake carefully for photos but once I got about two feet away it rattled and retreated into the rocks behind it. It continued rattling for several minutes while I made a waypoint on my phone and added notes. I walked past the same spot about an hour later and there was no sign of the snake. This was my first klaub in the Chiricahuas, which I was pretty stoked about; Coordinate Uncertainty in Meters: 29173.00000.

Occurrence Remarks: C. l. klauberi observed close to a trail in the Organ Mountains on a relatively cool, cloudy, and sporadically rainy morning. I originally spotted the snake coiled against a boulder at the base of a shrub for cover (Garrya wrightii). The snake rattled at me briefly when I approached but stopped and stayed incredibly calm after. Eventually it moved from where I first saw it and I was able to get my camera close for photos. I spent about 20 minutes with the snake, first taking photos and then just observing it before leaving it alone. This was only about two meters off a relatively popular trail in the Organs but nobody passed during that time, likely because of the rain.; Coordinate Uncertainty in Meters: 29120.00000.
