The highest peak of the Giant Mountains and the Sudetenland. Rock cone is built in the main part of metamorphic rocks called hornfelsami, and from the western side, at its base, with granite. This is the primary cause of the characteristic shape of Snow White. The building blocks of the main ridge Kakonoszy is less stable granite. Hence, the other sewn Karkonoszy have a much more radiused shape. Hornfels - the main building blocks of Sněžka rose from the transformation slate łyszczykowatego at the junction of the hot magma. The most inaccessible southern slope, cut by deep gullies. From the north is dominated by steeply sloping rock rubble, and to the east gently descends to the Solar Valley. The slopes of the northern and southern Śnieżka fall steeply to two deep glacial valleys: Łomniczki and Obří důl. Contrary to popular belief often repeated Snow White is not an extinct volcano. What its shape is the source of erroneous opinions.
There is here a specific climate similar to that we have the Arctic Circle. Therefore, at lower altitudes than elsewhere in these latitudes evolved alpine vegetation. They are responsible for the conditions. weather. The average annual temperature on Śnieżka slightly above 0 ° C, the warmest month is 10.6 ° C and the maximum temperature which was recorded in Snow White is 24.6 ° C (the latest record on July 28, 2013). Hence, the snow cover in arrears longer times between October and ends in May. During the year, the average rainfall exceeds 1,000 mm. However, the most characteristic of this peak are hurricane winds exceeding 80m / s, and frequent fogging (over 300 days per year). Long-term average wind speed at the Snow White is almost 12 m / s occur in the winter months when the monthly average of more than 25 m / s. White because of its location, length, and its continuous character, measurement sequence is a great place to study climate change. Minimized to almost zero are here influence local climate. On the basis of conducted here continuously since 1880, the observation can be concluded that at this time increase in the average temperature on Śnieżka exceed 1 ° C. Snow White is a place where you can watch rarely found meteorological phenomena like the fires of St. Elmo, Brocken specter, or Gloria.
