This is an aerial view from over Muir Glacier on April 11, 1968. In the distance is Riggs Glacier on the left and a portion of McBride Glacier on the right. In this early spring view, winter pan ice locks the prodigious output of ice from Muir and Riggs Glaciers into a single sheet. A great event in those days was the ice breakup, which resulted in a flush of ice down the bay, stopping most boating until things thinned out. By the middle of May, over a thousand seals massed in upper Muir Inlet, many of which were pregnant females using the ice as a refuge on which to bear their pups. Now the glaciers have grounded and this grand spectacle of ice and life is no more. Photographer: Greg Streveler
