Yes, I’d say it’s too early. It’s pretty typical for high school students (and college students) to change their minds repeatedly about their academic areas of interest, and what you think you want in a college now may not be what you’re looking for in a college two years from now.
That said, if you still want to draw up a tentative list, consider using geography programs as a limiting factor – assuming you’ll still be interested in geography as a senior. There are plenty of colleges with decent anthropology programs in the Northeast, but geography programs are quite scarce among small and medium-sized schools, as @merc81 noted above. (Side note: I did a fair amount of interdisciplinary work in geography as part of my PhD. I loved every minute of it and wish my undergrad had offered a geography program. It’s an extremely flexible major with good job prospects if you get the right training.)
Clark is unquestionably the best option among small colleges for geography, but it may not offer the outdoorsy environment you’re looking for.
