Mittagskogel / Kepa, Mountain summit in the Karawanks on the Austria–Slovenia border

Mittagskogel (Slovene: Kepa) is a 2,145-metre summit in the Karawanks, on the border between Austria and Slovenia. Its massif consists of main dolomite and Dachstein limestone beds rising between the Sava valley to the south and the Drau basin to the north. The steep northern face, resembling a rocky pyramid with a rounded summit, is a landmark in Carinthia.

The summit carries the boundary stone XXVI/214 at 2,143 m, set where the border follows the Drau-Save watershed along the crest. The mountain is recorded as Copan mons in a 1650 map, the earliest documented reference to it. The Berta Hut below the summit belongs to the Villach section of the Austrian Alpine Club.

The German name Mittagskogel refers to the sun standing above the summit at noon, as seen from Rosegg Castle; the mountain is a Zwölfer-Berg, a peak that marks midday. In Carinthian Slovene it is called Jepa, and a 1650 map records it as Copan mons, possibly from kopa, meaning a hay stack. The Slovene name Kepa is also used.

The normal route starts at the Bertahütte (1,527 m), owned by the Villach section of the Austrian Alpine Club and the mountain's only shelter; from there the marked path climbs the northeast and east sides and finishes along the southeast ridge. A separate trail follows the northwest ridge along the state border past the Kleiner Mittagskogel, and the northeast ridge route reaches difficulty grade I–II. On the Slovenian side the usual approach begins at the village of Belca in the Sava valley.

The summit is built of a 600–700 m layer of brittle main dolomite and thick-bedded Dachstein limestone; the hornstone limestone, Schler dolomite and Muschelkalk beneath form the peaks of neighbouring mountains instead. The border stone XXVI/214 stands at 2143 m on the watershed, with the summit cross just north of it at the top of the north face.
