(Muir Glacier, 1976) En 1976, el extremo de Muir Glacier se encontraba en un lugar muy distinto al de hoy. En aquel entonces, los glaciares Muir y Riggs eran glaciares de mareas activas. Entre ambos, sus icebergs proporcionaban un lugar para la crianza de cientos de focas de puerto. Solía ser durante un día inusual, al final del verano, cuando uno podía acercarse tanto, Ya que el agua estaba generalmente abarrotada de hielo flotante.

(Muir Glacier, 1976) In 1976 the terminus of Muir Glacier was at a far different place than today. Back then, Muir and nearby Riggs Glacier were active tidewater glaciers. Between them their icebergs provided an early summer pupping location for hundreds of harbor seals. It was a rare day, usually late in the summer, when one could get this close to the face because the water was usually packed thick with floating ice. Photographer: Karen Colligan-Taylor
