They pointed, like the sastrugi, or snow-waves of the Siberians, to the marchers of the lost company.
The surface was also perfectly level; there was not a sign of sastrugi in any direction.
Meanwhile the sastrugi grew smaller and smaller, and finally they disappeared altogether, and the surface became quite flat.
The light was bad, and steering had to be done by sastrugi and wind.
That day we encountered new surface conditions -- big, hard snow-waves (sastrugi).
The wind was practically along the sastrugi and the course was diagonal to both.
The surface, too, grew worse; nothing but sastrugi eighteen inches to thirty inches high and very close together.
They had kept a course roughly by the wind and the direction of sastrugi.
We are continually falling, for we are unable to distinguish the high and low parts of the sastrugi surface.
What the course was we did not care as we steered by the sastrugi.
