The Veliki Obrh Stream Goes Around the Hoar Frost Covered Lož Valley; Loška Dolina, Notranjska, Slovenija
08-January-2022: the Obrh stream with its two branches, originates in the East of this partially impermeable karst basin, comes from the subsoil of the Babno Polje basin, which, on the other hand, is mainly porous and permeable.
The difference in soils is probably the basis of the greater thermal excursion and liveliness of the less humid polje of Babno compared to this topographically very similar area.
The water it receives is mainly (a little part of) that of the forest of Mount Snežnik, whose area (Snežnika) is the rainiest in the Karst Region and among the rainiest in Europe (up to 3000mm/y); another small part comes from the reliefs to the North and North-East, Bloke and Racna gora.
Officially the Obrh is the first stretch of the "Many Names River" which then sinks again and re-emerges 4 more times, in as many valleys/basins, respectively with the names of Jezerščica/Stržen, Rak, Unica and Ljubljanica (it is one of the main karst springs of this right tributary of the Sava).
Therefore, the waters in the photo, less than 50 linear kilometers from the Adriatic, like all those of the inner part of the Karst Region-Notranjska, end up in the far Black Sea.
Seen this way, it looks like a peaceful country stream, actually giving birth to one of the largest and most complex karst cave systems in the world, largely unexplored.
