>>2169998I lived in az for a long time so I got all sorts of stuff, but my favorites from there are agatized/opalized petrified wood and fire agate.
I just moved to wi so my choices here are much more limited, I am gonna road trip out to Montana and states around there later this summer to go gem, mineral, and fossil hunting though.
BLM land is a good place to look for things, technically you are limited to 25 pounds a day and 250 pounds a year but I have never been bothered by anyone to check stuff like that.
That being said you arent supposed to sell public land finds for profit nor are you allowed to take any vertebrate fossils from public lands.
Picrel is fire agate
