The depth was -330m in previvious year in this cave, and they surpassed this limit with a digging, which was conducted from an underground camp. Now the size of the cave started growing, so it is quite prospecting.

This new cave might join Bretska Krępością cave, which was discovered previviously by them. This year a total of 200 speleologists worked in the Arabika area..
