I suppose we went a mile or more up this canyon. The tangle of down timber was very considerable in places chiefly where landslides had started on steep canyon sides. The trees were invariably uprooted, except in a few cases on landslides where they were broken off above the roots. I saw no trees snapped off at, above or below the middle except trees with rotten trunks. Only the large trees were thrown down except where a landslide brought down |
16_163 Nov. 11 -12, 1906 everything. Along the rift itself the greatest throwing down of the trees was just south of the Shafter ranch The rift here leaves the valley floor and strikes alongside the side of a hill parallel with the valley and some 40 to 60 feet above the valley floor. This side hill is forested with Douglas Fir, Tan Oak, Live Oak, Madrona with a mixture of small shrubs. The Douglas Firs were thrown down in greater numbers than all other trees. There were all uprooted. The reason for this is because of the shallow rooting of this species, having no tap roots and spreading out near the surace of the ground. |
