That's a beautiful flight - I assume you're in a little single?
Wind at that elevation will be serious. If it's a windy day, forget it. The turbulence will be bad, even more so in a small a/c.
You're in a designated remote area - you need survival gear. Especially at this time of year.
And look at areas for forced landings. Few and far between. Research your route on google earth.
Enjoy
