I can't think of anywhere where they are listed, but I'm a Southwest girl myself, and my favourite trips are the ones where I gave myself a little time, didn't just plan it all out, but just hit the road and watched the signs, stopping if anything caught my eye. I had an absolute ball once that way travelling through New Mexico, Colorado, and Utah. I saw Native pueblos, petroglyphs, national parks galore, etc. I also discovered a load of funny little burrito stands where I may have eaten the family dog, but oh, it tasted so good and funny little back road history spots that I never noticed before. I had been doing the drive through the desert for my whole life, but never seen those spots before.
I would say, don't stress about planning it. Get stuff for a picnic, and you will probably find some great spots just by following your gut--even if you don't, you'll have funny stories to tell about the odd spots you stopped when you ended up on some odd road that went nowhere
I'm so jealous. Say hi to home for me. I would really give anything to go back right now.
