PREVAILING WINDS AND SANDS The prevailing winds in this region would appear to blow from the west and northwest during the summer, winter and autumn. Though in spring, when they certainly are more violent, they no doubt come from the northeast, as in the desert of Lop. The arrangement of the sand here agrees perfectly with the law laid down by Potanin, that in the basins of gullies of the Desert Of Lop . Both sets of phenomena lie parallel to one another; from this we may infer that the winds which prevail in the two deserts are the same. Next comes, sharply demarcated from the zone just described, a more or less thin kamish Steppe growing on level ground; and this in turn is followed by another very narrow belt of Sand , immediately south of Achik-kuduk Finally in the extreme north we have the characteristic and sharply defined belt of kamish steppe, stretching from eastnortheast to westsouthwest and bounded on north and south by high, sharp cut clay terraces. "At the points where we measured them the northern terrace was 113 feet high and the southern 853/4 feet....Both terraces belong to the same level, and would appear to correspond to the shore lines of a big bay of the last surviving remnant of the Central Asian Mediterranean. At the point where I crossed it the depression was 6 to 7 miles, wide, and thus resembled a flat valley or immense river-bed." REFERENCES |
