45673. The entrance was passable, but barely and not for everybody. The passage, which extends as a meander along a nearly vertical fissure, in two interconnected levels, is part of the classic cave triangle in Lanski vrh (Vranja jama, Najdena jama, Skednena jama) and its continuation would greatly enhance caving knowledge of the entire area. It was discovered and explored in the seventies of the past century by the DZRJL member Jožko Jurečič - Koko, a grandmaster of popular physics who left us in an accident much too early. Further advancements in Koko's passage, invited by a strong air current, were attempted several times, most recently two years ago (described towards the end of this report), were hampered by very narrow entrance. This time Claudio, a true master of the cave digging craft, joined the effort and is seen here working on a treshold which makes entrance into the very narrow part of the passage troublesome.


 

 


 
45674. The author was holding the bucket steady while Claudio pushed rocks into it with his legs.


 

 


 
45675. Here he is clearing the pile of small stones at the entrance by throwing them out directly.


 

 


 
45676. View inside, to the squeeze entrance at the start of work


 

 


 
45677. Claudio and a rock he just rolled out.


 

 


 
45678. The author is filling a bucket by scooping small rocks with both hands until possible ...


 

 


 
45679. ... and completing the work with one hand (photo by Ludvik).


 

 


 
45680. View from the passage entrance towards the bottom of Vranja jama cave entrance hall, with Cox and Ludvik


 

 


 
45681. Two hours later the passage was quite passable - only the rocks at the bottom still remain to be moved out. A small "bucket-boat" (ladjica in Slovenian) will be used for the purpose.


 

 


 
45682. Satisfaction with today's achievement: Claudio, Cox and Ludvik in the entrance


 

 


 
45683. It was cold in the cave, and pleasantly warm on the sunny return trail.


 

 


 
45684. We also visited the old (2011) workplace in the southern wall of Radošca collapse, the Skrivni vhod mame Luše / Secret Entrance of Mama Luša (Cave). In the picture: selfie on the trail Članska vas shelter - Radošca cave.
