English: Road Junction on the Plateau. The view from here almost makes this part of Cornwall look flat, but it is far from it. Like much of Cornwall it is a plateau cut through by valleys, lots of them. Most old roads tend to stay on the drier plateau land where they can, and where they have to cut through a valley go straight down and up again at a steep gradient. These roads were originally meant to be travelled on foot or by pack animals. More recent roads tend to cross valleys diagonally as they were designed for wheeled traffic which need less steep gradients.
