These are from Kevin Weed of I17 North in Arizona in March 2018.
I have not been out here myself. I-17 is a relatively short
interstate only running from Phoenix to Flagstaff and it wound up
being one of the more scenic interstate drives I've ever
experienced. I think most folks who never make it to Arizona have
this perception that it is entirely (aside from the Grand Canyon)
nothing but flat saguaro cactus filled desert. While there is a
good amount of desert just like that in Phoenix and further south,
going north is quite different. as there is a gain of 5,284 feet
from Phoenix to Flagstaff, which sits at an elevation of 6,910
feet. As a result the whole drive north is up hill with one
instance of a 6% grade and another at a 7% grade.
This is by Exit 242.
