The Oregon National Guard helped rescue an injured snowboarder for the base of Broken Top.  The Deschutes County Sheriff's Office sent 22 volunteers to the Tam McArthur Rim area Monday afternoon.  The 44-year-old Bend woman was found on steep, snow-covered terrain, at more than 73-hundred feet elevation. After search and rescue arrived and provided immediate medical attention, an Oregon Army National Guard Black Hawk helicopter responded with a paramedic to help evacuate the patient.  She was flown to St. Charles Bend for further care.
