[3] At the end of the 19th and the beginning of the 20th century, a forest railway operated on its slopes, and during World War II, a tragic Hungarian plane crash occurred.

[3] On the southeastern slope of the mountain, remnants of a narrow-gauge railway network with a track gauge of 700 mm can be found.

During World War II, on 17 October 1944, a Hungarian transport plane, Junkers Ju 52, crashed on the southern slope of the mountain while flying from Hungary to Kraków via a detour over Moravia to avoid Slovakia, where the Slovak National Uprising was taking place.

[7] The plane came under fire from infantry while flying over Olomouc and, continuing in difficult weather conditions, crashed into the mountain.

[8] It is a very expansive mountain with a domed summit area and a primary, curved ridge extending southeast to northwest for about 8 km.

[13] Kazatelna is a group of rock formations[14] that stretches in an arc across the southeastern slope of the mountain at elevations between 750 and 1,050 meters above sea level.

[17] The summit area of Černá stráň is densely forested with spruce, and it is also covered with common vegetation of the Hrubý Jeseník region, particularly European blueberry.

There is a triangulation station on the summit, marked on geodetic maps with the number 7, at an elevation of 1,236.83 meters above sea level, with geographic coordinates 50°07′17.99″N 17°04′39.71″E / 50.1216639°N 17.0776972°E / 50.1216639; 17.0776972.

From this junction, a road (marked with two horizontal white stripes) initially leads towards the summit area, followed by a path that must be followed for about 960 meters.

[13] In addition to the main summit, the Černá stráň massif includes four lower secondary summits:[8] Geologically, Černá stráň belongs to the unit known as the Keprník Dome[18] and is composed of metamorphic rocks, primarily gneiss, orthogneiss, phyllites, and phyllonites [pl] (biotite, chlorite, muscovite), mica schists (staurolite, andalusite, garnet, sillimanite), and sedimentary rocks, mainly limestone.

This area was established to protect rock formations, geological features, plants, and rare animal species.

[8] The Slunná stráň Nature Monument is located at the foot of the slope, near the flowing Novolosinský potok and the Přemyslovské sedlo pass, at elevations ranging from 715 to 846 metres above sea level, and covers an area of 38.5 ha (95 acres).

[8] The nature monument was established on 12 December 2018 by the Czech Agency for Nature Conservation and Landscape Protection (Czech: Agentura ochrany přírody a krajiny České republiky), aiming to protect the landscape of a complex of meadows, interspersed with stone blocks and pastures, home to special species of oat-grass and animals, along with their habitats.
