Here are some suggestions for conservation, if you are going to enter this cave:
Clean up after people, whether it is you or someone previously there.
Do not leave V-threads (abalacovs), they will stay here forever entombed in ice, and that is called littering.
Use ice screws, when possible.
Add glow-sticks or small lights to gear left from a pulldown, so you can retrieve them in the dark.
Never defecate in the cave. Nobody wants to climb a Poo-cicle.
Do not vandalize the formations, or walls of the cave.
Take nothing but Photos and Memories, and remember to play safe as Cell phones etc, do not work underground
