8 July 4-1918 Little Rive. Rivis really the dips are at first gentle to about 200 feet and then more steeply to 500 or 600 feet. Above the latter is the fault-line scarp face for about 500 to 600 feet more. Still higher there is a more mature and smoothed (glaciated) topography for from 100 to 300 feet more, and it continues to rise back of this to a preplained surface that maybe at 1600 or more feet. [Diagram] Today we saw but one place that I thought might be a moraine. It was near Overfell. All the other valley sides appear to be made of stream boulders and sand clearing from the Long Range side of but little Windings river probably due to its older nature. Not rounded by water. It is stream material and not ice born debis. Here and there one sees large erratic but those seen are in the depths of the valley and are the erratics of the glacial period. While the other material came out of the hanging walls while those had their local glaciers, and enlarged torrential streams. The hanging walls are the pre-glacial walls aggrandized deposited and sharpened by the retreating moring ice. Their side are straight and no marked spurs extend into them. If the fault-line scarp is jumping into feet there has been since the country was glaciated an elevation of the Long Range of at least 500
