As the river Soča made its way towards the sea, it came across a crest (called Polovnik) that made her take a turn. The highest point of the same crest (1772 m) is Krasji vrh, spreading 9 km from east to west.
Polovnik is actually only the name of the west part of the crest. The higher, east part, is called Morizna, but many call the entire crest Polovnik.
