Glacier pool is far too narrow and deep for comfort

This glacier pool scares the bejesus out of me. Something about the narrow-ness and the deepness of it is freaky yet beautiful to look at. I've never seen a pool of water shaped like this before. I wonder if it's possible to go diving in? I give the guy in the video props for even getting up close to it! Even though I'm a good swimmer, I wouldn't go near this wild looking pool of water with a 10 foot pole.

From IG:

"Ever see anything like this?! This glacier pool is perfectly flush with the ice level making it look like frozen ice almost"
