Hranicka Propact 265m

I believe that was the deepest cave dive in Europe:

Kirss: video shows Hranicka Propast cave between 220 and 265m depth. photography helps us use the ROV to penetrate the deepest part of the cave. the movie was filmed with two cameras mounted on a helmet at different angles so that I have a bigger range of the image. How we see on depth 230m is a large window in the rock and behind it a large hall. Below 240m the cave is doing extensive and resembles a bell. This bodes well :)

Neat to see a tree 200m deep in a cave !
