men-an-tol. the stone of the hole. zennor hill. not the men-an-tol of the madron stone circle but ‘a stone of the hole’ never-the-less. a double stack of tor stones situated just below the summit of zennor hill. a solutions basin has worn through the depth of one stone and begun working through the stone below. that these stone existed on the neolithic is borne out by its incorporation in the unique men-an-tol stone circle at madron. . . . #men-an-tol, #stonestack, #holedstone, #thestoneofthehole, #zennor, #zennorhill, #neolithic, #deeptime, #stonemonument, #prehistory, #westcornwall, #westpenwith, #solutionsbasins, #rockbasin, #tors, #torstacks,
