Her photographs captured an era in Great Plains history. Photographer Evelyn Cameron lived in eastern Montana, starting in 1891. She began taking photos a few years later, using the large equipment associated with glass-plate photography. For over 30 years, she documented life in the wide open spaces - from deer, eagles and sheep to the human activities on the ranch and in town. Her contribution to preserving images of turn-of-the-century life was not fully appreciated until her prints and negatives were discovered in the 1970s. She also wrote extensively in diaries, which have been preserved for the public at the Montana Historical Society.

At 6 p.m. Thursday, March 28, historic interpreter Mary Jane Bradbury will "become" Evelyn and give a first-person view of life in early Montana, using the Cameron diaries as source material. The free presentation will be in the upstairs main display area of the Hamilton museum at the corner of South 3rd and Bedford. Bradbury is a scholar and actress and member of the Humanities Montana and the Colorado Humanities Speakers Bureaus.
