The long slab was airlifted to one of the wildest parts of the moor in November 2001. Hughes's friends have kept its location secret, fearing it would become a shrine.
The grave of his former wife Sylvia Plath, in Heptonstall, West Yorkshire, has become a shrine to admirers of her work. Their daughter Frieda and Hughes' widow, Carol Hughes, would not comment on the discovery of the Dartmoor memo rial, which is more than three miles from the nearest road and in a part of the moor still used for live firing on the army's Okehampton range. It was discovered by walkers visiting nearby Cranmere Pool.
Ian Cook, a close friend of the poet, said: "Ted Hughes left instructions in his will for me to locate a spot and he gave directions for it and I carried that out in a very appropriate and beautiful space.
"His instructions were that it should be near the rising of the rivers Taw, Dart, East Oke ment and Teign. The area is wild and wonderful and exactly right."
