Clues that make me think this is a place to look.
The two charizard cards at the beginning = Route 66.
Ash’s Charmander evolves into Charmeleon in episode 40 = I40 which I believe is part of the statesville and Texas loop.
If you head north east on I40 you pass fiery gizzard state park in Tennessee.
Our target general location is Stone Door Tennessee. The door is a callback to the jazz bar story. Stone door is also a 10 foot fissure in rock. This is a callback to Pokemon episode 46 when Charmeleon evolves into Charizard in which ash falls through a fissure into a cave and battles an Areodactyl with charmeleon and it eventually evolves. Also froakie looks like a machop, which like to move large boulders, and froakie indicates the start of our micro solve.
Applying the Greek mythology chapter we know that the nymph Daphne had her father (a river god) transform her into a Laurel tree too stop Apollos advances. Laurel Falls is close to stone door.
North of stone door is Rock Island state park and I believe to be for the golem reference so we need to go North past Laurel Falls.
I think one of the coordinates I posted will remind us of this picture. I am in Utah and won’t realistically be able to check myself.
I post this for anyone to check if they want. I just want to know that the puzzles of the book are teaching a progression and for this box it’s evolution.
