Thanks for enjoying it along with me. It's lonely out there. The whole area from northern AZ across to the Four Corners is desolate, windy, vast, majestic and makes one feel tiny indeed. Like a tiny little cactus, haha.
For fun, I put together a list of all the stuff I saw over the three days, in order of time:
Escobaria missouriensis navajoensis
Pediocactus peeblesianus fickeisenii
Opuntia basilaris longiareiolata (from the car)
Echinocereus engelmannii variegatus
Escobaria missouriensis marstonii
The Navajoan Desert (if one can even accurately use that term) has incredible speciation, somewhat similar to parts of the Chihuahuan. What's amazing is the short distance between dramatically different plants, such as the relatively few miles between Pediocactus bradyi and Pediocactus paradinei, growing in dramatically different habitat. The geographically isolating features and microclimates have given rise to a lot of variety over a very small area.
