National parks quarters game 2018

For this game, it is very easy to cheat because you can get the solution in 5 seconds by Google.
But let's try to be fair and see who will find the final design of the quarters this year
4 answers (block Island seems offside)

I don't want to cheat, so I will just put forward my favourites:

Pictured Rocks: No. 4

Voyageurs: No. 11

Cumberland Island: No. 17

Apostle Islands: No. 21

(Somehow I feel it's redundant to put humans in images of coins celebrating natural landscapes)

zero good answer
At least it eliminates some possibilities

I love mastermind!

2 - 8 - 15 -23

Nice progress
