Snakes in the rain

Well, ok, one snake. But no question about the rain. I encountered this extremely lethargic specimen on a track leading up from the middle of nowhere to the back of beyond. Since it was at risk from the occasional farm truck, mountain biker or hiker, I decided to remove it - carefully - to a slighty less exposed spot which hopefully might get some sun soon. I’ve no idea what kind of snake it is - or even if is actually a true snake. It seems to have a more lizard-like head. Possibly a viper, though.
