You can "Google" these and view "Images" in left sidebar and view "Maps" to see if they are within your travel route, so you can see them as you travel along and not have to jump back and forth. You'll probably be following I-10 from Phoenix over to New Orleans.....We made a similar trip as you are contemplating but, from WV......consult a map or, like us, you will miss lots of sights you'll drive by and not know it 'til you get home, LOL!!....
Just take the little cursor "hand" and drag the map to view then click "satellite" or "Earth" view to see what is actually there. Click to "zoom" the area you want or just enter the site you want to view....
