Fun, weird, helpful, or little known fact
As its name suggests, this arnica is fuzzy on its stems and leaves, grows taller than our other high-elevation arnicas, A. latifolia and A. rydbergii, usually has three flower heads growing at the top, and its pappas (bristly parts under the disk flowers/button) are tannish, not white, especially with age. It emerges as the common A. cordifolia, Heart-leaved arnica, is receding.
