Mount Dolmed was a mountain in the Ered Luin.
Mount Dolmed loomed over the only known pass from Eriador into Beleriand. It was here that according to the Dwarves two of the Fathers of the Dwarves, the founders of the Broadbeams and the Firebeards, awoke. Their descendants later established the Dwarven cities of Nogrod and Belegost.
The two cities were established on the Eastern side of the mountain. Just a little of North-east of Dolmed was Belegost, and a little to the South-east was Nogrod.
However the maps of the Third Age, show a prominent unidentified mountain exactly on the location of Dolmed in the map of Beleriand. This coupled with possible misunderstanding Tolkien's maps, therefore make it possible that Dolmed survived.
