Chests!
I think the site is in dire need of things for players to open, I'm think chests, loot bags, old bottles, geodes, you name it!
You got your tiers of chests going from small to big or varying amounts of age/shininess, a dirt y sack of food to small pouches filled with a little bit of currency (ranging from 10-1000 pebbles, a knuckle, or a moon shard or two)
They should have a rare chance of appearing from doing multiple things:
Fishing- bottles, boots, chests, old crab pots/nets
Mining- artifact troves, geodes, gold mining gear from previous miners
Hunting- lots of opportunities to find cool loot there, chests to weapon caches and food bags in between
Campaign- either enemies can drop openables or there could be small events where your wolf can find, these need to be dropped at a much lower rate than the other areas due to how easy this could be to exploit with how quickly you can currently grind
wolf releasing- perhaps a small bag of the wolfs previous possession with the quality of the goods inside being determined by the wolf's level upon release
and finally the Gauntlet! This place should have the highest chance of you getting some kind of openable as a way to incentivise players to use the gauntlet more
