the terrain near Sonoma is very similar to much of Northern New Mexico. There area right at Sonoma has more interesting sand and wind blasted rock formations.
The terrain of new Mexico varries a lot. If youre wanting to keep the breaking bad vibe then you're going to want lots of scrub brush, some sage, the occasional cholla cactus (pronounced choy-ah) or small yucca, and prickly pear. The soil can be rocky but not usually large visible rocks. The floor is not often sand but more dirt and clay dust, ranges from the redish brown to mud brown.
The real plains of NM are to the far east of the state by the west Texas border, and aside from the occasional hill, are indistinguishable from west Texas.
For good reference google "northern chihuahuan desert" the biome is a bit different than the Sonoran desert which is to the west and covers most of Arizona.
Not that most people would care or notice mind you.. I just spent 25 or so years living there.
