No Mount Cave Diving In Wisconsin
No mount cave diving is extreme diving.
This type of diving that involves navigating underwater passages of a cave that are so small that a diver can not mount tanks on his/her back.
Helmet off to squeeze through
In this particular video the divers are seen entering a subterranean cave in what seems like a most unlikely entry point, through a small crevice from which a stream flows.
I couldn't imagine being in such a tight space. One of the divers had to remove his helmet just to squeeze through the rocks.
These passages are so small that just viewing the video can make you feel claustrophobic.
