The Ungagon Mountains is a mountain range separating West and East Soltenna. It extends from northeastern Qonklaks to central western Liosol and divides Hyuy En into two geographically separate regions. Bordering the mountains are the Rapheng Mountains on the south and the Laun Mountains on the east. The Ungagon hosts most of Soltenna's highest peaks and all of the region's six-thousanders except Mount Bevaseiyrna, including Soltenna's second highest point in Mount Dyinsup whose height above sea level reached 6,552 metres (21,496 ft). Its English name is derived from the Tolec name Ungu Agon meaning "gold mountain(s)".
The Ungagon's geological history dates back to the (Paleozoic) era when the mountain was formed. It formed largely through collision of the (West Soltennan) and Rietic plates during the Ungagon orogeny, which also formed the Rietic Mountains that is believed to have been the part of the Ungagon before a rift valley comprising Lake Soltenna was formed around 50 million years ago, splitting the Rietic eastwards. This split increased volcanic activity of both ranges. The Ungagon's highest point, Mount Dyinsup, is estimated to move at an annual rate of 1.4 mm (0.055 in) upwards and 3.5 mm (0.14 in) northwards.
Most volcanoes in the region are now dormant, but is still subject to regular strong earthquakes from its tectonic activity. Earthquakes on the mountain range are known to have caused damage indirectly through avalanches.
Cold continental and semi-arid climates dominate the climate of the Ungagon. Average annual temperature in the lakeside Hux Mlak, in comparison, is 14 °C (57 °F), while in Khin Mlak, average annual temperature falls to 6 °C (43 °F). Furthermore to the Mount Dyinsup slopes, average temperatures reached as low as −5 °C (23 °F).
Snow caps of the Ungagon Range feed three major rivers: the Zranx, Methinya, and Mang rivers. Due to the cold climate, the Ungagon highlands are overall scarce in vegetation, with most of the area being above the tree line. The Ungagon populace are thus reliant on these rivers to live and are scarce in numbers. Although minor, rain shadow effects caused by the Ungagon made some areas west of the range—northern Hyuy En and extreme eastern Karduv—drier than the eastern counterparts, which comprises the western half of the Lake Soltenna basin.
