"Even in the last years of her life, Calderón was determined to preserve and pass on everything she knew about her language and her culture. Together with her granddaughter, Cristina Zárraga, she created a Yaghan-Spanish dictionary that includes a CD where some words can be heard. They also published a book of indigenous legends, songs and stories called Hai Kur Mamašu Shis (I want to tell you a story). Her daughter Lidia Calderón promised, as a member of Chile’s constitutional convention, to defend her mother’s legacy and the Yaghan language, despite the challenges that this entails: 'Even if with her death we lose a wealth of empirical knowledge, especially valuable in linguistic terms, the possibilities for the rescue and systematization of the language are open.'"
