Hand prints, fin prints, etc are everywhere in caves especially Peacock, Ginnie and other really popular sites.
Why not take a 12" or 18" drywall knife and smooth it out similar to shackle on drywall (similar to the 5th and final cote over sheetrock)? Caves with flow will return to normal very quickly but even caves that have very little flow with return to normal thanks to mother nature in a few weeks?
A repaired hand print looks better then the actual print...no?
