Heahyrne (Eo."Exalted Peak") was the Rohirric (post-T.A.2510) name for one of the major peaks of the White Mountains adjacent to the western reaches of the Mornan .Towering above its neighboring peaks, and capped with year-round snow, this mountain joined the northern wall of the Ered Nimrais facing Calenardhon . Although it was visible from southern Gondor, its aspect from that side was not remarkable enough to attract a name for itself, save among the Orodbedhrim who ranged exclusively in the high mountain vales.
