| Summary: | Alaska Glacier Retreats. ALASKA GLACIER RETREATS. Fifteen years ago a member of the United States geological survey mapped the front of the Barry glacier, which is in the northwest corner of Prince William sound, Alaska. In 1910 it was found that the front of the-glacier had gone back about three miles from the position it occupied in 1809. B. L. Johnson of the geological survey examined the front of the Barry glacier in the fall of 1914 and determined that the total retreat of the glacier between 1910 and 1914 appeared to be about 8,200 feet a retreat of four and one-half miles, in fifteen years. A short account of the retreat of this glacier by Mr. Johnson has just been published,as professional paper 98 C. It Includes a sketch map showing the position of the glacier front in seven different years and several reproductions of photographs of the glacier.
