This photo shows Plateau Glacier in Wachusett Inlet on June 5, 1967. By the time of this photo, Plateau Glacier was a mere remnant of the great icefield that once included the Carroll Glacier system and the vast Muir system once roamed on by John Muir in the late 19th century. The low gradient and lack of heavy crevassing shows that by 1967, Plateau Glacier was no longer fed actively, but had become a stagnant mass being melted from above and nibbled away from the side by sea. A decade later the ice was gone and Wachusett Inlet stood in its place. Photographer: Greg Streveler
