She’ll almost certainly get into Utah (though not Honors). They are keen to add more OOS kids and they admit over 80% of applicants (pretty much anyone over 3.2 GPA). I don’t think there’s much need to search out a bunch of other safeties in the Mountain West. It’s a great school for outdoorsy kids, D18 loves it there and I’m hoping S23 will consider it. You can’t beat the skiing (30 mins away), but don’t forget the climbing, backpacking, rafting, etc also. SLC is a nice town with a booming economy and easy to fly into (it’s a Delta hub).
Utah is an easier admit than Boulder, and also much cheaper since you can get residency and instate tuition after the first year. No chance of admission at BYU though.
