It's supposed to be Eryn Garan. The modification appears if the word is used as an adjective loose from the noun it's referring to. That's why Caradhras as Redhorn is correct yet if you want to just say red mountain it wouldn't become Orod Caran, it would be Orod Garan, because Caran is used as an adjective. It's also the reason for names like Tol Galen and Eryn Galen as stated before. So HighElvenDoge you might want to read up on your elvish cause you're spouting bullshit. Caran is the base, Garan the modified form. You went on 'oh but Caran is used much more often' yes, it is because in all the examples you gave it is attached to a noun, which means it won't be modified. Technically it would even be Eryn Gerain as Gerain is the plural of Garan. But since Eryn (the plural of 'orn'=tree) has lost it's original plural meaning of 'trees' and is now used as the singular word 'forest' it means that it's just Galen.
