Treasure Maps in Central Plain are easier to find compared to the earlier two maps simply because the clues are pretty straightforward.

1. Lonely Compartment
Map location: Talk to a Scavenger near a gigantic tree at the edge of the farm. Give him marinated eggs in exchange of the treasure map.
Dig location: It’s near Western Outpost at the big rock. There’s flag marking the location.
2. Damaged Billboard
Map location: Go to Hawks Market and you’ll see a Scavenger. Approach him and give him Vegetable Stew Food in exchange for the map.
Dig location: Near Glen Station towards the north of the map. You’ll see the Damaged Billboard and there’s a campfire near the container.
3. Scarecrow
Map location: You’ll see a Scavenger standing nearby. Approach him and give him a bandage in exchange for a treasure map.
Dig location: Go to the farm slightly southwest of Hope and look for a Scarecrow.
4. Yellow Hot Air Balloon
Map location: Inside Hope’s Gas Stop, there’s a safe for you to crack.
Dig location: Go to the open field in front of the Western Outpost and locate the yellow hot air balloon. The dig location is at the flag.
5. Greenhouse
Map location: You’ll come across a bus with a tree dropped on it near base #74
Dig location: If you look inside one of the two greenhouses located north of Glen station, the treasure is on the cement bags.
6. Trash
Map location: Go to the secluded house on the hill towards the east of Rosedale. You’ll see a booklet pages on the coffee table inside the house.

7. Don Quixote

11. Ravings of an Engineer
