A cave from which spills a huge waterfall, this is where MountainPack stays during the birthing season. The waterfall flows from a spring deep within the cave and into a small pool outside the cave before tumbling down the mountain. It is not as dangerous as it seems to raise pups here, for the pool outside the cave is very shallow and even though the waterfall falls from it, it falls over a raised ledge which not even the strongest current could pull a pup over.
