~ Velebit / South Velebit / Sveto Brdo-Vaganski Vrh group ~
Beware of these beasts! On the places where warm air flows from inside Velebit to the surface such huge holes open in snow. Such holes are present all along the highest peaks group between Struge and Sveto Brdo. Holes are as deep as is snow cover and very dangerous, especially if hidden with fresh snowfall. This one is 6m deep!
It is interesting that when there is no snow no openings are visible on the surface.
