Angelica pinnata is a relatively uncommon species, most widespread in the mountains of west Wyoming, but also found in scattered locations north nearly to Canada and south into New Mexico. The leaves provide the easiest means of identification as they are less complex than those of many other angelica species, usually (pinnately) divided only once, into a small number of narrow, coarsely-toothed leaflets, lacking stalks. The lowest pair of leaflets may be divided a second time.
Plants are slender, with upright, ridged stems topped by a compound umbel of 6 to 25 rays. Pedicels are of unequal length; the longest is about 3 inches. Stems have a purplish sheath near the base. There are no bracts below the umbel, or beneath the individual clusters. Flower petals are pure white in color, and hairless.
