13 August 1993:   Muir Glacier.

S. Hall Young wrote the following in his 1915 book "Alaska Days With John Muir."

"Returning down the bay, we passed the largest glacier of all, which was to bear Muir's name.  It was then fully a mile and a half in width, and the perpendicular face of it towered from four to seven hundred feet above the surface of the water.  The ice masses were breaking off so fast that we were forced to put off far from the face of the glacier.  The great waves threatened constantly to dash us against the sharp points of the icebergs."
