This idea came to me when reading
Tesha's Sea Trade idea, so figured I would share it. I occasionally dig when I visit islands or new places, and while I mostly don't find anything, sometimes I do. I would be really interesting if there were hidden chests or supply caches that were generated randomly about the islands, in both wilderness and non-wilderness locations. These could be dug up using a shovel, and working in a similar nature as the Globes of Shifting Contents, would potentially contain valuable items or regular items.
There could be different types of chests or caches, which would not be apparent until they were dug up and opened. Some could be empty, the contents having rotted over time. Others could be trapped, simply a decoy to lead a would be thief to their demise. Then there could be those that are the real deal and hold either supplies or valuable treasures.
I think it would do a lot for the exploration aspect as well as encouragement for Seafaring in general.

Personally I'd do it by randomly finding treasure maps while performing other tasks (walking, bashing, questing, Seafaring activities), and having those offer some kind of clue to point the way. That gives the activity more of a timeframe, making it less of a needle in a haystack thing.
One other problem is that while it would be an interesting activity, I doubt they're interested in creating a new way for people to gain valuable rewards just for the sake of it. You'd have to justify how it would benefit the game. Ship diving puts more vessels on the ocean to drive piracy and conflict - this would have no such benefit.
Or the ability to pull up randomly spawned wreckages from the ocean floor to try to scavange for treasure or other things, with the chance of having to fight of some wave of creatures or another.
As to valuable rewards for the sake of it, the goodies dug up could be less gold/heron feather types of things and more cask of rum or a battered figurehead types of things.
