This one I know – I think, my guess is Cholla 🌵cactus
The various species of Devil Cholla are all Club Cholla, so-called because they have club-shaped joints with well-defined tubercles. Devil Cholla have no sheaths on spines. All are low-growing, often forming thick mats that can be impenetrable. Spines come in all colors, but can be sharp as daggers.
