As fast as the fine dry snow fell, it drifted and packed itself into the coulees, gulches, and depressions, filling them to a depth of a hundred feet or more. The divides and plateaus, and other exposed places, were left almost bare, except where some mound or rock or bit of sagebrush created an obstruction, about which the eddying currents piled snowdrifts which rose week after week to huge proportions. On the river bottoms where the sagebrush was thick, the snow lay level with the top of the brush, then drove on to lodge and pack about the cottonwood trees and beneath the river-banks, forming great drifts, extending here and there from bank to bank. The blizzard abated, but the icy cold did not; another blizzard came, and another and another. Save as it was whirled by the wind, ultimately to become a part of some great drift, the snow remained where it fell. No momentary thaw came to carry away a portion of the country's icy burden, or to alleviate for a few hours the strain on the snowbound men and women in the lonely ranch-houses. On the bottoms the snow was four feet deep. November gave way to December, and December to January. The terrible cold persisted, and over the length and breadth of the Bad Lands the drifts grew monstrous, obliterating old landmarks and creating new, to the bewilderment of the occasional wayfarer. Blizzard followed blizzard. For the men and women on the scattered ranches, it was a period of intense strain and privation; but for the cattle, wandering over the wind-swept world of snow and ice, those terrible months brought an affliction without parallel.
