Today in 1987, Hulda Crooks, affectionately known as Grandma Whitney for scaling Mt. Whitney 23 times in her golden years, successfully scaled Mt. Fuji in Japan. At 91 years old, she became the oldest woman to do so. Crooks scaled over 100 peaks between the ages of 65 and 91. She was also active in her community, mentoring children and teaching them the benefits of being in nature.   Image Credit: Sioux City Journal
