"Cupeño means 'one from Kupa.' They are actually the Kuupangaxwichem, the 'people from the sleeping place.' The sleeping place was their traditional homeland at Warner's Hot Springs, but following the massacre there the survivors were relocated (along with Luiseno families) to what is now the Pala Reservation. Limu is conducting linguistic research in the language of the Kuupangaxwichem to develop resources that will assist their revitalization efforts."
