About 15 miles prior to Flagstaff in northern Arizona, this is the town the song tells you not to forget (that song being Bobby Troup's "Route 66"). Wynonna Judd certainly didn't. Born Christina Claire Ciminella, she adopted "Wynonna" as her first name after hearing the town's name in the famous track. Apparently, spelling was not a factor.
To follow Route 66, you can go through Winona (formerly Walnut Creek) by leaving I-40 at Exit 211, or staying on the freeway for a few more miles and getting off at Exit 204; either way, these older sections of Route 66 end up at U.S. 89, which you join and follow into Flagstaff from the northeast.
In some areas, you're really close to hugging Mount Elden, a volcano peaking at 9,299 feet above seal level. Mount Elden is a pretty dominant piece of the landscape, visible from most points in the Flagstaff area.
