Hey Jackson - first off, congrats on deciding to go out on your first sheep hunt. That's a big commitment and you'll have a blast regardless of how many sheep you see.
There's literally decades worth of research one can do on finding sheep in Alaska. Coming from my own experience, it is 100% possible to research some solid areas through hours and hours of reading, looking at maps, talking to the local community, and hiking (a lot) during the Summer. It's pretty competitive, so have fun scouting and researching, but please just be careful not to accidentally blow up someone's spot on the internet.
Good luck out there, it really is a great challenge.
