The summer of 1886 was hot and dry, and by autumn, the range was almost barren of grass. The cold and snow came early, and by January, record-breaking snowfalls blanketed the plains, forcing the already weakened cattle to expend vital energy moving through the snow in search of scant forage. In January, a warm Chinook wind briefly melted the top layers of snow. When the brutal cold returned (some ranches recorded temperatures of 63 degrees below zero), a hard thick shell of ice formed over everything, making it almost impossible for the cattle to break through the snow to reach the meager grass below. With no winter hay stored to feed the animals, many ranchers had to sit by idly and watch their herds slowly die. “Starving cattle staggered through village streets,” one historian recalls, “and collapsed and died in dooryards.” In Montana, 5,000 head of cattle invaded the outskirts of Great Falls, eating the saplings the townspeople had planted that spring and “bawling for food.”
When the snow melted in the spring, carcasses of the once massive herds dotted the land as far as the eye could see. One observer recalled that so many rotting carcasses clogged creek and river courses that it was hard to find water fit to drink. Millions of cattle are estimated to have died during the “Great Die Up” as it came to be called, a darkly humorous reference to the celebrated “Round Up.” Montana ranchers alone lost an estimated 362,000 head of cattle, more than half the territory’s herd.
Besides sending hundreds of ranches into bankruptcy, the hard winter also brought an abrupt end to the era of the open range. Realizing they would always have to grow crops to feed their animals, ranchers decreased the size of their herds and began to stretch barbed wire fences across the open range to enclose new hay fields. By the 1890s, the typical rancher was also a farmer, and cowboys spent more time fixing fences than riding herd or roping mavericks. Belatedly, settlers realized that they had to adapt to the often-harsh demands of life on the western plains if they were to survive and thrive.
