Stewart can be identified in photographs of Childe's 1927–1930 excavations of
Skara Brae in Orkney, alongside other female archaeologists who had previously been dismissed as visitors or tourists, but who can be seen holding trowels, which indicate their active role in the excavations. During the early stages of
Perth's urban development, Stewart quickly became aware, and was pivotal for the awareness, of the archaeology lying underneath the local streets and buildings. She was responsible for the creation of various groups which would monitor these developments and take the opportunities to further explore local archaeology. Stewart also carried out important work with her research into the location and distribution of cup-and-ring rock art, resulting in a large amount of information which she was still compiling by the time of her death. She was elected vice-president of the ELP in 1933. Later, she also acted as the Vice-President and President of the Scottish Regional Group for the Council for British Archaeology (later Archaeology Scotland). She also edited their flagship publication,
Discovery and Excavation in Scotland. Stewart had a great interest in sharing Scottish archaeology and was involved with various local communities. She served on many local and national committees, established the archaeological section of Perthshire Society of Natural Science (1948) and was a founding member of the Perth Civic Trust which she chaired between 1970 and 1972. At a time when archaeology was more interested in gaining a more professional attitude, Stewart was encouraging of the involvement and training of students and others, as well as volunteer participation in excavations. For example, during the excavations at the four-poster stone circle on Lundin Farm Road (1963), she divided the site into sections to "give everyone experience of digging". and the
