Split-rail fence
A split-rail fence, log fence, or buck-and-rail fence (also historically known as a Virginia, zigzag, worm, snake or snake-rail fence due to its meandering layout) is a type of fence constructed in the United States and Canada, and is made out of timber logs, usually split lengthwise into rails and typically used for agricultural or decorative fencing. Such fences require much more timber than other types of fences, and so are generally only common in areas where wood is abundant.
