Diversity of subterranean deposited forms is visible in this pano. Stalactites and stalagmites are a deposition of calcium carbonate but the big rocks are from the crashing roof of this huge underground hall. It is huge hall with a height of 40 m, length of 50 m and width 40 m. This hall is the end of the Barefooted Tunnel (Bosonogi rov), which was discovered in December 2004. The tunnel is 500 m long and it starts at the Windy Waterfall in the main tunnel of the Nova Križna jama, which is about 1400 m inside the cave. Nova Križna jama was discovered in 1991 and the first entrance into the cave was discovered in 1992. This is the World's biodiversity, the 4th underground habitat known so far. From the entrance trough the narrow vertical passage to the Barefooted Tunnel, passing some with millions brilliants like decorated passages and finally to the last hall takes about ten hours of climbing – and the only way back out is the same way.
