Great pictures!
Gypsum is pretty fragile rock. Easily scratched with the finger nail and broken. It's generally formed from shallow seas. I'm not completely certain, but I imagine that once the rock is saturated it would crumble fairly easily with percolation.
Nice photos.
Is the gypsum relatively solid compared to limestone or does it crumble easily with percolation or to touch?
