Wright's Fishhook Cactus (Mammillaria wrightii) -- I think.

Growing naturally (not cultivated) in pinyon-juniper woodland at Quarai, Salinas Pueblo Missions National Monument, Torrance Co., New Mexico, USA.

After the area was ditched, it's clear almost all the tamarack died and the rich soil was invaded by a solid wall of buckthorn. Canopy trees are almost non-existent and native swamp species just barely hang on. A travesty of "land management".
