It sounds like you will need some good financial aid. In addition to the traditional LAC’s, you might look into Warren Wilson College, which is a work college (with forestry being one of the work options - over 600 acres of managed forest on campus) with some very interesting anthro/geography related programs. It’s in Asheville, NC, the “gateway to the Blue Ridge Mountains” - very beautiful area with milder winters than New England and amazing outdoor opportunities.

In the more traditional colleges, there are a lot of “usual suspects” in terms of New England and Upstate NY “woodsy” schools that meet full need: Colby/Bates/Bowdoin, Hamilton, Colgate, Williams, Dartmouth, Middlebury.
Colorado College could be worth a look too - their block plan is particularly conducive to intensive field study program in anthropology, geology, etc… and plenty of woods/outdoors!
Whitman is a great outdoorsy school too - I suspect you could find several majors of interest on their list: https://www.whitman.edu/academics/departments-and-programs
Lastly, for a public option beyond Indiana, the Utah public U’s offer good merit aid and also offer a path to residency after the first year, which could make years 2-4 cheaper than your own in-state public U’s. U of Utah, while it’s in the major city of Salt Lake, also puts some of the most breathtaking outdoor recreation in the country at your fingertips. The Honors College is excellent https://honors.utah.edu/ and provides a smaller-college experience within the larger university (including year-long honors projects called Praxis Labs) … and there is a very impressive Geography department https://geog.utah.edu/

Hope that gives you some ideas to work with!
