All That Glitters is one of the many Strange Missions that receive special rewards for completing them. This quest will give you two gold bars that can be sold for $ 1000.
To get the quest, you need to travel to the southern part of the map, to Flatneck Station. From here, drive west to the Dakota River, where you will meet a lonely person.
Interact with him and you will find out that this is the famous explorer Maximo Cristobal Valdespino. You will need to buy a Jack Hall Gang Treasure Map from him for $ 10.
First treasure
Located slightly south of the center of the map. You will need to travel to Caliban, which is just below Valentine. Here, head towards Caliban's Ridge, but make sure you are approaching Caliban from a northern direction.
When you get to the top, you will see a small camp, but instead of going to the camp, you will need to walk straight along a narrow path on the side of the cliff.
Just follow the path and climb the small wall. Once you cross it, you will see a small gap in the wall - the treasure is here.
Second treasure
Located in the northern part of the map. You need to travel to Cottora Spings in the northern part of the map.
Here you will find an open plateau made of stones. Go to the large rock, on top of which there will be a treasure.
Third treasure
Located in the northern part of the map. Walk east of the Grizzly Region and to the left of it you will find Lake O'Creagroon.
In the center of the lake you will find a small island - a treasure on it. You will find two bars that can be sold for $ 500 each.
