This map is based on our research. We have checked its accuracy to Level 3 ecoregions. Although this plant occurs somewhere in each of these regions, it may only occur in a small part of some or all of them.

This species occurs mostly in the eastern portion of the Canadian Rockies; we found one 1974 report that appeared to be from the foothills just east of the Rockies but were unable to verify the accuracy of its location.

↑Notes

We recommend against using the common name "snow arnica" as it more often refers to Arnica griscomii subsp. frigida which was once considered a separate species, Arnica frigida C.A.Mey. ex Iljin.
