In all the histories and geographies of the island of Númenor, only two mountains were named. The first was the famous Meneltarma, the Pillar of Heaven that stood in the central highlands. The other was far to the north, near the island's North Cape, with its eastern flanks forming sheer sea-cliffs. That was Sorontil, the peak of the Forostar.
Sorontil's name was never given an English form, but in translation it would be 'Eagle-horn', an appropriate name for a mountain whose crags were home to countless Eagles. In the early history of Númenor, Tar-Meneldur built a tall tower in the vicinity of this mountain, though we are not told whether this actually stood on the slopes of Sorontil itself.
