After retiring from the business world, Maisie became interested in Archaeology. From 1986 to 1991, Maisie worked in various field excavations, including work in California, New Mexico and Valle de Guadalupe, Baja California. Maisie found an interest in what became of the artifacts and therefore found archival work in museums. Maisie has worked with San Diego History Center Photo Collection since1993, and historic archaeological collections at SDSU and Fort Guijarros Museum Foundation, where she was the Archaeology Lab Supervisor from 1994 to 2012. In 1995, Maisie started leading the lab component of the Ghost Ranch Summer Archaeology Seminar. She enjoys this very much and looks forward to each new year of discovery.
