The Lost Riches event is underway in Genshin Impact, and Treasure Area One is now available for exploration. You will find it at the Falcon Coast, a small group of islands in the mouth of the river to the southeast of Windrise in Mondstadt.
When you get there, a golden circle will appear on the map, and here is where you will find all the treasure and the Iron Coins. You will need to equip your Treasure Seeking Seelie, which you can do by opening your Inventory and going to the gadgets section.
Use the Seelie and then walk around the area to find all the treasure, netting yourself 60 Iron Coins that you can use in the event shop to buy all manner of items. You can find all the treasure locations marked on the map below, or use the video above if you need help tracking them down in-game.
The white pickaxe symbols on the above map each denote a treasure location. Remember, you will need to visit Ulman at the Stone Gate in Liyue and speak with him to start the event. He will give you a Treasure Book, and the Treasure Seeking Seelie, and then you will be free to start the event.
Each day, two new areas will appear in the game where you can find the treasure and the Iron Coins, and there will even be special treasure areas as well. The Iron Coins can be used to buy Hero’s Wit, Primogems, Mora, Mystic Enhancement Ore, and a special Seelie from the event shop.
