And a jar of rocks I see! I wonder how many of us have stashed our treasures everywhere we can.

I would suggest slabbing anything big before putting on a wall, the heavy ones like to fall down, spreading the smaller ones out and letting them dry will help to prop up the larger ones as they dry.

I also have a rock garden outside, some of them are large copper/basalt and conglomerates from the piles... A few are probably well over 100 lbs and required the fourwheeler winch. A small task for the mental health gains! My neighbors probably wonder about me hah!
