Are you open to liberal arts colleges? Someone with more expertise than me should respond, but I believe at least one of the elite LACs in the northeast has an especially strong environmental science program (Williams? Middlebury ? Colby?..also, Macalester in St. Paul, perhaps?) Grinnell in Iowa tends to be fairly generous with aid and is an overall strong school, though I don’t know anything about its environmental science offerings. Many of these schools are seeking strong, active students who would bring geographic and racial diversity to campus.
