For any young whipersnappers that like to hike at 10 to 13 thousand feet, Highway 50 runs through Sevier River valley.
If you follow it into Nevada there is a park "Great Basin National Park" . They grow Bristlecone pine trees way up high.
They are some of the oldest living thing on the planet. If I remember there was one 5000 years old. You can even chuck a few snow balls in the summer. It's one of the must do's.
One of the other memories I have of that trip,
Even though you just rebuild your chevy 350 into a 383 stroker, roller cam, Dart heads, If you have a carburetor, and a 12 foot camper, It aint gona run very good at 10 thousand feet. They have an upper parking lot, so you don't have to walk so much. I could have walked faster than my truck would go. Thats why I put fuel injection on the jeep.
Another "must do" while you can hike is go to the Mt.Timpanogos cave. Then there is the sand dunes, the High Uintas, yea, I do miss living in Utah. I just wonder if that warrant is still active, and on the books.
