Emigrant Wilderness

Rules
- Standard sudoku rules apply.
- Nurikabe: shade some cells so that no 2x2 region is completely shaded or unshaded, and all shaded cells form one orthogonally connected region.
- Arrows: arrows have two different meanings depending on whether or not they are on shaded cells:
- The digit on a shaded arrow is the number of shaded cells visible in the direction of the arrow, including the cell with the arrow. Unshaded cells block this vision.
- The digit on an unshaded arrow is the size of the orthogonally connected region of unshaded cells to which it belongs. In this case, the direction of the arrow has no meaning.
Below is an example grid, to see the ruleset in action.
The name of the puzzle is a reference to the Emigrant Wilderness in the Stanislaus National Forest, in the northern Sierra Nevada mountain range. This wilderness is notable for its numerous alpine lakes amid the granite landscape. Often setters theme their nurikabe puzzles as several islands in the ocean, so I wanted to turn it around and think of it as a collection of lakes!
Solution code: The digits in the first row.

Very nice! It was very smooth once I reread the rules and realized it was nurikabe and not yin-yang ^^;;
