Slanské Hills  The Slanské Hills (in Slovak, "Slanské vrchy") is a range of mountains in eastern Slovakia, one segment of the Mátra-Slanec Area of the Inner Western Carpathians. The area is named after the nearest town in the southern portion, Slanec. The range is approximately long, side, and extends southeast of the city of Prešov, between the Košice Basin and the Eastern Slovak Lowland. The mountains average high, with the highest elevation at Simonka, (where 700 healthy, mature elms were discovered in 1998). The mountains are forested, with several mineral springs, and resources such as gold, silver, and antimony. Passes through the mountains include the Herľany Pass and Dargov Pass ("Dargovský priesmyk"), site of a significant World War II battle.
