Thanks for all the tips everyone. We had a great time! I was so amazed to see cacti in the wild like this. They are not just native to home improvement stores!
The first was just East of Ruidoso, NM on highway 70 up on a hill. I don't know which Echinocereus it is. It had a lot of small, dried up flowers which made me think viridiflorus type, but it's awfully spiny.

The following are just West of Roswell up on a hill off of highway 70, I was getting a little discouraged seeing just Opuntias (not that they aren't wonderful) and then I saw one Echinocereus, then another, then a E. horizonthalonius, and then when you get the search image you see that they are all over. Wonderful! The highlight of the trip, I couldn't be happier.
I guess this is reichenbachii*, but the finer points distinguishing reichenbachii, pectinatus and rigidissimus escape me, at least without the flowers.
*edit = apparently this is Echinocereus dasyacanthus, thanks John and Peter

I love these little guys. My daughter's hands for scale.

Here is Echinocactus horizonthalonius. Really cryptic but they were all over, usually hiding by some dried up bush.

Thanks again on all the tips on where to look. It's amazing all the microhabitats. The hills East of Roswell were sort of dried mud and I only found Opuntia. Roswell and El Paso are now may favorite towns. Maybe I can retire there someday...
