Last night after stargazing, I decided to shine my UV flashlight around. I found this interesting dried up river bed that had these mounds of fluorescent rocks. Would anyone have any ideas what this is? I posted this in r/whatsthisrock as well, but figured you guys may enjoy it as well 😁

Wow! I had no idea there were fluorescent bits in rocks!
Where did you get the sst20 4500k? Or is it a 4000/5000k mix?
