In 2010 we were able to make a trip down to southern Arizona. While on a hike in a beautiful rocky area, we were privileged to find this little gem. It rattled, which is probably what caused us to see it. Otherwise, it would have probably been sufficiently camoflaged for us to have missed it and walked right past. Hopefully we will be able to get some more video of montane rattlesnakes in 2011.
