Copperhead + Timber Rattler

So I live in the Chattanooga Valley of the Tennessee River Valley and our local is the water moccasin. I was on a hike through a canyon with the girlfriend one day and she almost stepped on one that was sitting on the trail curled up and extremely well camouflaged. On our way back through that same area I stopped off on a rock to piss and noticed something moving where I was peeing it was 3 water moccasins curled up in a leaf pile when I stepped off the Rock and turned around there was one more right by my foot that I stepped on the tail of. I quickly pulled my foot back up as the snake struck luckily it did not chase me and simply went under the rock I had been standing on. Suffice to say the girlfriend has not wanted to go back hiking on that trail.
