The territory west of the Oder river stretching from the town of Opava up to Bílá Voda was confined by the Jeseník mountain range of the eastern Sudetes in the south, separating it from Moravia, and the Opava river in the north.
It evolved through specialization of an isolated population of Campanula scheuchzeri, an Alpine species, which expanded to the area of the Sudetes during a colder period, probably the last ice age.
For the next 20 km it merges with the Polish - Czech Friendship Trail at Szrenica and runs on the main ridge along Polish and Czech border, to reach its culminating point, the highest peak in the Sudetes - Śnieżka.
Reluctant to return to the USSR, he continued flying as a test pilot and was killed on October 20, 1922 near Trutnov, Czechoslovakia when his Potez aircraft crashed in the Sudetes mountains.
