The Kortos Mounts occupy much of the inner, lesser inhabited and still wild portions of the Isle of Kortos, and are among the most jagged and highest-known peaks in the world. The highest peak, Arazlant Mox is more than five miles high. The mountains are typically forested at lower altitudes but barren and icy at their peaks. Some of the peaks are volcanic. Despite passage through most of the range being nearly impossible, rare metals and gems are still mined from them, and are then exported to other parts of the world.
