"itoid gneiss - Its surface is entire slopes are [see h. 73] covered with angular blocks, 6 to 10 inches across and larger - saw one I was particularly interested in the dastrugi developed [everywhere almost] over the surface of the glacier and on the ice cap. Those of the glacier were more varied in form and more charac teristic perhaps than those of the ice cap, the snow left on the glacier being hard and more closely compressed than that of the cap - through greater force of the wind perhaps. The dastrugi of the glacier were in two layers, at least, the lower pointing east and the upper southeast. Noted concavities like little cirques, concave toward the wind and bounded by vertical walls one - two inches high. Much erosion of the packed snow by the sand-blast action of the driving hardened snow particles. In many places saw little cliffs 2-3 inches high, vertical tow ward with slopes at bottom like the talus slopes of a rockcliff but with growth in opposite direction - that is, they were caused by snow particles driven against the vertical walls. Layering action of the wind on the snow evident
