Filled with the spirit of their ancestors, Penobscot Indian Nation members and other Wabanaki gathered early one recent morning before the sun rose to embark on a journey that took them down the same paths their forefathers used. Butch Phillips, 70, a Penobscot elder, led one of many groups that left Indian Island last week for the annual Katahdin Spiritual Run, a 100-mile trek by canoe, bike and foot to Mount Katahdin, a sacred site for the state’s four native tribes.
