Hrubý Jeseník (sometimes calledHigh Ash Mountains in English;German:Altvatergebirge orHohes Gesenke,Polish:Jesionik Wysoki) is amountain range andgeomorphological mesoregion of the Czech Republic. It is located in the east of the country in theOlomouc andMoravian-Silesian regions. It is the second highest mountain range in theCzech Republic.
According to the most probable theory, the name has its origin in the wordjasan, i.e. 'ash'.Jeseník (respectivelyJesenný potok) was first the name of a stream that flowed through an ash forest in a valley. The name was Germanized toGesenke (i.e. 'slope') and used as a name of a small town that was founded in the valley (but later disappeared), and then it was transferred first to the valley, and then to the whole mountain range. Later the name was changed back to CzechJeseník. Jeseníky (plural form of Jeseník) is a collective term for an area that includes the mountain ranges of Hrubý Jeseník (literally 'rough Jeseník') andNízký Jeseník (i.e. 'low Jeseník').[1]

Hrubý Jeseník is amesoregion of theEastern Sudetes, which is part of theSudetes within theBohemian Massif. It is the second-highest mountain range in theCzech Republic. There are 56 peaks with an altitude of at least 1,000 m, which are spread evenly throughout the territory.[2]
It is bordered with theNízký Jeseník in the southeast, with theZlatohorská Highlands in the northeast, with theGolden Mountains in the northwest, and with theHanušovice Highlands in the southwest.
Hrubý Jeseník is further subdivided into the microregions of Keprník Mountains, Medvědí Mountains and Praděd Mountains.[2]
The highest peaks are:
A distinctive feature of the relief is also Mt. Medvědí vrch, which at 1,216 m (3,990 ft) is the highest mountain of the Medvědí Mountains microregion and is among the mostprominent mountains of Hrubý Jeseník.[3]

The territory has an approximately circular shape. Hrubý Jeseník has an area of 530 square kilometres (200 sq mi) and an average elevation of 887.6 metres (2,912 ft).[4]
Several rivers and streams originate in the mountain range. The most important are theDesná and the sources of theOpava River. The only notable body of water is theDlouhé stráně Reservoir.
Due to the mountainous character of the landscape, there are no larger settlements here. The largest settlement in the territory isVrbno pod Pradědem. The town ofJeseník is located just beyond the borders of the mountain range.
