In August and September 1921, Arnold Arboretum dendrologists Susan Delano McKelvey and John George Jack made a botanical collecting expedition to Montana’s Glacier National Park. Accompanying them were McKelvey’s teenage son Delano, and her assistant, a Mr. Dall (who’s first name we do not know).
Leaving New York on August 21, the group traveled by train past the Great Lakes, westward through the Dakotas, arriving at Glacier National Park several days later. McKelvey kept detailed notes of the flora she observed from the train car windows along their route.
Largely unexplored from a botanical perspective, Glacier National Park proved to be a diverse region. McKelvey and Jack made seed and live plant collections from 95 woody and 244 herbaceous taxa of plants. The majority of collections were also represented by herbarium vouchers, such as this Douglas maple (Acer glabrum var. douglasii) or this grand fir (Abies grandis).
McKelvey’s journal and collection list mention 22 distinct collection locations, all within the state of Montana, and most within the boundaries of the National Park. She often associated her collecting locations with the nearest named lake, including Lake McDonald, Swiftcurrent Lake, and Iceberg Lake. Photographs taken by Mr. Dall, accompanied McKelvey’s detailed trip journal.
The trip to Glacier National Park served as McKelvey’s introduction to botanical exploration. The skills she acquired from working with John Jack on this trip would serve her well in the future as a plant explorer, author, and authority on the flora of the desert Southwest.
Back in Boston
Fifteen of McKelvey’s collections from this expeditions were accessioned and planted out in the Arboretum’s Rockery along the north side of Valley Road. Unfortunately, none of these plants remain alive in the landscape today.
