Outhouse

The wind continues to come from your left, off the water. It is probably the reason you didn't notice the smell of the outhouse you see just ahead of you.

There's only dense woods beyond the little building, effectively blocking you from going west around the island.

You call out, but nobody answers from the outhouse.

Though you don't need to pee at this moment, maybe you should check the outhouse. Otherwise, head back toward the cabin east.
