Harry John and his dog Tazlina lead the way as he and John's brother Fred John Jr., back center, complete their 375-mile walk from Valdez to Fairbanks at the Chief Andrew Isaac Health Center in memory of their mother Katie John Monday afternoon, June 12, 2017. It was the third time in four years the trio has completed a walk. In May 2014, one year after their mother, Katie John, died, the brothers walked from Dot Lake to Anchorage to protest former Gov. Sean Parnell’s request to the U.S. Supreme Court to overturn the Katie John case, the substance ruling stemming from a 1990 lawsuit that resulted in stronger Native subsistence fishing rights in Alaska. In May 2015 they walked from their home village of Mentasta to Fairbanks, a 270-mile trek. They walked not only to honor their mother but all mothers and grandmothers who have passed on traditions to their children, calling it a “Walk for Tsucde,” which translates as “grandmother.” This year's walk, which John Jr. said will probably be the last, began in Valdez on May 20.
