There are two rocks inscribed by Henry Kendall in the Gosford area. One, below the obelisk on the edge of the highway has his
initials "H.K" (top row of photos), while the other has his full surname ("H. Kendall") (bottom row of photos).
The later was discovered in about 1908 by a resident called William Moore, and is also called "Kendall's Chair" because of the shape of the rock.
There was a rock-pool in a glen,
Beyond Narrara's sands;
The mountains shut it in from men,
In flowerful fairy lands.
But once we found its dwelling-place --
The lovely and the lone --
And in a dream I stooped to trace
Our names upon a stone.
There has been some debate over the years as to which of the two engraved stones the poem refers to, and whether Kendall's Chair is in fact an engraving by the poet at all. Personally I think it probably is.
