The exception proves the rule. DV is beautiful because of its extreme geography (11-14k foot verticality). The Mojave/GB lacks the flora/fauna of the Sonora (eg saguaro), the color of the Colorado, and the elevation of the Chihuahuan.
The worst roads trips in the US are the I-10 from Palm Springs to Phoenix, the I-80 from Reno to SLC, and the I-40 from LA to Vegas. I've done them all (on many different occasions); the Mojave is a colorless, lifeless, drab, boring & depressing desert.
But based on tons of other comparative data I'll take any Arizona desert to Cal/Nev desert.
Oops!
I just remembered Lake Havasu.
Oh well, beauty is in the eye of the beholder, I guess. I haven’t done the Reno to SLC trip, but have the others. It’s desolate, but I like it. I’m in Palmdale right now, but the only thing ugly about it is the cultural garbage that’s slopped over from LA.
That's some of my favorite country. Some eyes just can't "see." I like the Sonoran desert too.
