| Summary: | (3)round topped hills & ridges & wide smooth bottomed valleys. All these have the form of greatest strength with reference to the action of an over flowing ice sheet that no doubt covered all the country like a mantle as Greenland is covered today & also the lands about the south pole. This accounts for the occurrence of gravel on hilltops & hillsides & for the gold contained in it. The rounding of the moraine material the making of angular masses into smooth pebbles & cobbles was done by the streams that issues from the ice sheet & separate glaciers when it was melting & withdrawing at the close of the glacial period. At the fronts of many of the glaciers of S.E. Alaska you may see all this work being done just now. Your trip in from Chilcoot to Dawson & down the river was very adventurous & interesting.
