After about the fourth time of getting stuck, instead of doing lookahead I started guessing so I cannot determine the solvability of this puzzle.

I *think* I just used moderate lookahead (it needed some 2-way logic on the top 2 rows, to get going). I really should pay better attention, now that I have the power to determine these things. :)

I'll try solving again, without using visual clues.

Yep! After LL runs out, the highest column value of the top 3 rows are (nearly) all 1s 2s and 3s, so there needs to be some summation/edge logic done. I was able to mark a square in R1 C10, and the rest of the puzzle completed nicely with LL.

Found to be solvable with moderate lookahead by kristen.

Tough one, definite lookahead required. Still enjoyed it.

A nice engaging puzzle. I saw what the main part of the picture was. I imagine other states can get/have gotten this treatment & I'd like to find those puzzles!

Edge logic on the top row worked for me. I placed the 3 black squares I could, then noticed a quick contradiction if c24r2 was a black square (the next part also follows if c24r1 is a dot.) That placed the 6 on the right side and made edge logic at the top. R1C15 has to be a dot, otherwise we have 3+/5/6.

Loved the puzzle!!!! Only thing wrong with puzzles like this is when the last dot or box is put in and it's over.
