Genshin Impact has a variety of World Quests that provide insightful information about the many regions of Teyvat and the characters living in it. Some of them are hidden and only appear under certain conditions, and some others are locked behind Adventure Rank and Main Story progression, but all of them reward the player with useful items such as large amounts of Mora, Ascension Materials, and even Primogems.
Lost In The Snow World Quest Walkthrough
To unlock this quest, you need to talk to Joel inside of the Dragonspine Adventurer Camp, as depicted below:

Follow the Snow-Covered Path to search for Joel's father and read the "Neatly-Written Note" on the ground.

Continue to the western slope of the mountain and use Pyro to melt the snow covering the "Neatly-Written Note" on the ground and then read it.

Head for the summit and break the rock wall to access the cave. Read the "Scribbled Note" next to the pot, and report back to Joel with your findings. Don’t stress over choosing a dialog option, the result will be the same.

After completing the quest, you can place Berries inside the foxes' bowl as per Joel's father's wishes. Doing so for four days and then opening the chest on the 5th day will give you the achievement "Untellable Tale" and give you a Precious Chest with a Crimson Agate inside.
