The calving ice on the W. Twin Glacier, feeding into the Taku River, has the brightest blue of the day--even on a gray day. Seen on an excursion with the staff of the Taku Glacier Lodge, early Sep. '13. The rock in the middle of W. Twin's 'terminal' begins the process of busting up the glacier which the lodge staff appreciate as they look for smaller blocks of ice to haul back to their iceroom. That's been the method of refrigeration for several decades at the remote site that is now a featured tour by seaplane from the Juneau waterfront and cruiseships. 150 grilled salmon meals are served daily during peak season.
