Well, if you're turning South to go to Sedona and TX, you'll go over the "new" bridge and bypass the Dam. Newish overlook on the AZ side.
Sunset Crater near Flasgstaff, Walnut Canyon ruins, Petrified Forest as you get to New Mexico border area.
We had some decent Mexican food in El Reno OK.
After that, you're on your own!
Oh, cars usually go South from LV to Mexico, not North to Canukia. Your buddy moving back?
Meteor crater east of Flag about 37 miles?
Worth the short detour.
