Boulders
(Published on 17. December 2021, 10:00 by Mark Sweep)
This is a new puzzle type I came up with recently. Hopefully you will enjoy it!
Rules
Shade some boulders in the grid, such that no two boulders touch each other, even diagonally. Boulders are orthogonally connected groups of shaded cells, without enclosing any unshaded cells within them. In addition, no two boulders in the grid have the same size. Clues denote the amount of cells in the 3x3 area centered around it, including itself, that are part of boulders.
Example
The puzzle
Solution code: The lengths of consecutive lines of shaded and unshaded cells in rows 4 and 7. The example would be 62 512.

Great puzzle! Surprisingly tricky until you find the right idea, but very smooth and satisfying from then on.
