Sorry, had these drawn before the shrug suggestion.
As is traditional for a dwarf on new lands, you symbolically strike the earth. It leaves a dark gauge in the wet beach sand, but the sand will probably smooth itself out soon enough. Having done that, you retrace your steps back to your boat to see if there's anything from it you might need.
Wooden oar. Built for rowing rather than fighting, it has enough weight and hardness for a good smack, but the length makes it slightly awkward and it may break easily if struck.

The thought crosses your mind to try to take apart the boat for materials, but then you decide you may need it again. Besides, the boat is glued together with resin, making it waterproof but hard to disassemble.
You decide to take a walk around the island. At first you walk cautiously, as the place is rather eerie with all the fog around, but by the time you walk back around to your starting point, you haven't seen anything.
It's completely barren. Nothing strewn around, not so much as a piece of driftwood. Not a sign of life. You suspect that no one has ever been here before.
With nothing much outside, you head towards the cave. As you step towards the entrance, you feel it again. The calling. What you've been journeying towards must surely lie inside.
You enter a narrow passage, stone walls with a deep sandy floor. It turns right and slopes down, but not into complete darkness; there is a faint, flickering glow ahead. At the bottom of the slope two strange sights greet your eyes.
The passage emerges into a small chamber, ankle deep water around the sides but dry in the middle, where rests a ring of campfires, the source of the light. They cannot have been burning long, but aside from them there are no signs of recent activity. You'd expect to see the imprint where someone had been resting, as travelers often make rings of fire around themselves to protect themselves from the night, out in the open, but the sand is untrodden. Strange.
