This is one of the thousands of pieces broken from inside Crystal Cave.
The damage is an insane amount for me to understand but there are devoted people who are slowly making progress placing these pieces back together and gluing them.
The only thing I can think is that these avid conservationists must be steller at jigsaw puzzles.
My hubster Kit, I am proud to say, is one of the lucky few that got to help with part of the on-going restoration. The most amazing bit is that one day he got to help and actually found a piece that matched.
The heads of the project informed him that if you find one piece in a week you are doing well.
The dash 4 written on the formation means it was (illegally) selling for $4.00
Don’t worry. The turds were caught.
