You may want to take a side-trip out of Jackson into the Wind River Range and find a ranch that rents AWD vehicles and explore the Continental Divide.

When my daughter was 15 we rented a Mustang convertible and explored the same region you are targeting and ended up spending a couple of days in Dubois, WY exploring the Divide on off-road vehicles. To say the least, it was a memorable adventure!

The last time I was through that area was on my trip back to CA from VA with the 997. The temps were well below freezing but the roads were empty (mid October 2014) and while Chief Joseph was already closed, it was difficult to leave that area and I ended up spending an extra day there...it really is a very special place and you and your family will have a blast!
