It’s never too early to start thinking about college! Anyway, I like the Hamilton and Middlebury suggestions, though even if they were to come through with all the financial aid you would need, there will still be travel costs - just somethig to keep in mind. With Middlebury, you would have “outdoorsy” right there at your feet, and probably a bit more selection as far as fields of study and available courses go. At Hamilton, you’d have to travel a little bit if you were wanting to get to the mountains, but the campus itself is lovely and contains its own arboretum/hiking trail. I believe there is also an outing club that I’m sure provides lots of fun adventure trips. And you’d get some good doses of snow in the winter too. “The Hill” is just beautiful in the snow. Nearest ski slope is about an hour to an hour and 1/2 away. Hamilton does not seem to have a geography department - seems like geography falls under “Environmental Studies” (You would have to check out the course catalogs to get a sense of the offerings.) But my impression has always been that it has a rich anthropology department - and it’s probably intimate enough that you would be able to direct your own course of study and perhaps even research.
Good luck in your search and in the rest of your high school career!
