Snowdon

Snowdon is made up by 4 cairns running roughly North-South. They are a prominent horizon feature viewed from the East as far as Ashburton.
The cairns increase in diameter towards the South and the 3 southernly cairns are spaced about 120m apart from each other, whereas the northernly one is about 175m away from the nearest neighbour. The most northenly cairm is not on the OS map.
