DAVIS: MOUNTAIN KANGES OF THE GREAT BASIN. 151 suffered some carving, as is shown in Figure 9, where some of the ter- minal facets are enlarged. The moderate dissection of the large facet by small ravines results in the development of several little basal facets along the fault line, where they form the truncating terminals of several. Figure 9. Diagram of dissected terminal faces of main spurs, showing small basal facets between short ravines; drawn on a larger scale than Figs. 6-8. little spurs. These basal facets are of importance in this stage of dis- section, for they have suffered the least change of any part of the moun- tain front. AVe are thus led to conclude that the features of special significance as the necessary result of long-continued faulting, persistent into the recent period, are : first, the sharp-cut, narrow-floored valleys which have already been considered; and secondly, the large and small termi- nal facets of the spurs, whose bases show a notable alignment all along the mountain front. If faulting be supposed to cease after the stage of Figure 8 is reached,.
