| Summary: | is evidently effected beneath or on the surface of the glacier by the streams, some of them torrents in size and force. On account of the rough crevassed condition of the glacier, the surface water finding its way to the bottom far back and cutting and keeping open channels of considerable size. Into these wells, mills, crevasses and under channels, the surface moraine matter falls and is well ground over and over again before it is finally discharged a thoroughly milled grist. The finest flour, superfine, is carried out to sea many miles, 20 or more from the mouth of the Stickeen, where it slowly settles and forms rocks of various kinds, the origin of which with their varying texture and their imbedded fossils, is seldom guessed. { Sketch: 1st of the larger Stickeen Glaciers 15 miles up descends within 200 ft. sea level. } The middlings https://scholarlycommons.pacific.edu/jmj-all/2430/thumbnail.jpg |
