I went back to finish the survey of a cave this weekend that I'd not been to in a year and we found most of our flagging taped stations had disappeared.
Because of this, we had a hard time figuring out where our tie-in station was. At first we thought it was animal caused, but at multiple stations, some very difficult for any animal to reach, we found the tape mostly gone. Sometimes the tape was visible as small bits sprinkled around where the station was, so it seems likely some natural process destroyed our tape.
Has anyone seen this before?
Does anyone have any good ideas for what may have caused this?
Although light does get fairly far into this cave due to the vertical entrance these stations were all fully in the dark zone so UV should be discounted.
