Interior Secretary Ken Salazar, National Park Service Director Jon Jarvis and Gov. Christine Gregoire (D-Wash.) are scheduled to attend the memorial service this afternoon at Pacific Lutheran University in Tacoma. Salazar also has ordered the agency’s flags across the country to fly at half-staff in Anderson’s honor.

Anderson, 34, is survived by her husband, who is also a park ranger and her two young children. The National Park Foundation, a private charitable organization, has established a memorial fund to benefit Andreson’s two young children.
