-COLORADO COLLEGE, in Colorado Springs. One of the best private colleges near good ski country.
-MIDDLEBURY COLLEGE, in Vermont.
Ok, it's Vermont, but the school is academically amazing.
Otherwise you'll probably want to go a step down in levels of academia with public universities in Montana, Colorado, Utah or Reno, NV. The Univeristy of Denver would be a good one, too.
UVM (That's Vermont) is a good school, too. But, it's Vermont, again.
Those are the ones.
