There is a map in the Pokemon Diamond/Pearl Guide Book.
There is no such thing as Iron Mountain, but there is such thing as Iron Island. If that is not what you are looking for, then there is also Stark Mountain and Mt. Coronet. For iron islands, you have to get to Canalave city, then on the western side, keep on walking down until you see a sailor with a boat. Talk to the sailor. Iron islands is where you see Cherrim, and get a Riolu egg.
