Dear “Pawn Stars” stars … next time you’re gonna TRASH your campground, make sure there are no cops around … because in the State of CA it’s a misdemeanor crime!!!

Rick and Corey Harrison — a.k.a. the pawn shop boss and his son — went camping in Glamis, CA over Thanksgiving weekend with some friends … problem is, we’re told they left the place a mess.

Law enforcement sources tell TMZ … cops discovered A TON of trash where the History Channel stars camped out … specifically beer cans, garbage and a bbq grill … enough to fill up 10 TRASH BAGS.

FYI … We’re told cops KNEW the reality TV stars were the ones camping in the trash spot — and causing the mess — due to a previous encounter that weekend.

Dumping trash in the campgrounds is illegal and NOT taken lightly … in fact, we’re told law enforcement slapped the guys with a huge fine … to the tune of $1,000 a person … and that’s NOT negotiable.

Corey Harrison tells TMZ, “We left the campground before our buddies did and they were to clean it up and apparently didn’t follow through. My father nor I were cited.”
