Keprník, Mountain summit in Hrubý Jeseník, Czech Republic

Keprník, called Glaseberg in German, is a gneiss and schist summit of 1,423 m in the Keprník Highlands of the Hrubý Jeseník, the fourth-highest peak of the range. Its treeless top is a cryoplanation terrace with a frost-riven rock outcrop about 20 m long, and no marked trail reaches the summit itself.

Keprník lies on the historical border between Silesia and Moravia, with the main summit on the Moravian side. Its German names Kepernik, Köppernik and Glaserberg appear in older records. A stone monument with a memorial plaque to the Silesian writer Hermann Löns was erected on the northern slope on 26 September 1935.

The summit's bare summit meadow, called hole, allows circular views over the whole Hrubý Jeseník and toward Králický Sněžník; in clear weather the Krkonoše and Beskydy are visible, rarely the Malá Fatra, Vysoké Tatry and Ještěd. Since 1946 a circular directional stone has stood at the viewpoint.

No marked trail reaches the main summit; the red ridge route and a green educational path cross the summit plateau, with a junction sign giving 1423 m. Access is easiest from Ramzová, Ostružná, Branná and Červenohorské sedlo. Because the summit lies in the Šerák-Keprník national nature reserve, leaving marked trails is prohibited.

The summit plateau is a cryoplanation terrace: a bench-like step of flat surface and scarp, topped by a frost-riven crag. Below the peak stand the so-called flag spruces and two peat bogs, and the slopes hold several hard-to-reach waterfalls.
