| Description: | Logan Rock, W. of Roughtor, Camelford. Looking N. Granite tor ('Logan rock'). A further stage than that seen in A483 and A484. This stone does rock with a very small 'push' in pressure. The two specially hardened faces probably existed underground and the dust has been blown away. Logan stones are rarely developed, because one or other of the surfaces gets 'crushed' by the weight of the stone. |
