mountain range on the western fringe of the Carpathian Mountains that forms the northern segment of the boundary between Moravia (Czech Republic) and Slovakia. The ridge of the Javorníky peaks—the highest, at 3,514 feet (1,071 metres), is Velký Javorník, overlooking the village of Velké Karlovice—divides the Bečva-Oder river systems to the north and west from the Váh River to the east. Climate and altitude are conducive to sheep raising, and winter sports thrive throughout the region.
