Nothing they can and should do about it... it's a natural feature and process of the cave... should be left alone and hope that it will re-emerge the following winter.
Big Brush Creek Cave in Utah has one similar (if not larger) and it comes and goes ... depending upon if the conditions that cause it to form are met.

Some people take things a bit too seriously.
