This prickly thistle grows from desert scrub up to the upper conifer forest. It's called Jackson Hole Thistle (Cirsium subniveum, also Greene's Thistle, Cirsium inamoenum by Flora of North America). Apparently the name confusion is partly due to some unresolved topics about this species. Sometimes plants can be funny like that. Despite botanists not being able to decide what to do with it, the Jackson Hole Thistle has decided to take up residence in many of the western states.
This is a view looking down on it.
The flowers can be white to lavender.For more info on Jackson Hole Thistle, click here.
