On the 30th day of April, our reinforcements having joined us, we gladly resumed our march for Utah, and at about one o'clock encamped upon the ridge that divides the Arkansas from the Platte rivers. The day was bright, cheerful, and pleasant, the atmosphere soft, balmy, and delightful. The fresh grass was about six inches high. The trees had put forth their new leaves and all nature conspired in giving evidence that the somber garb of winter had been cast aside for the more verdant and smiling attire of spring. Our large herds of animals were turned out to graze upon the tender and nutritious grass that everywhere abounded. Our men were enjoying their social jokes and pastimes after the fatigues of the day's march and everything indicated contentment and happiness. This pleasant state of things lasted until near sunset, when the wind suddenly changed into the north. It turned cold and soon commenced snowing violently, and continued to increase until it became a frightful winter tempest, filling the atmosphere with a dense cloud of driving snow, against which it was utterly impossible to ride or walk. Soon after the storm set in, one of our herds of three hundred horses and mules broke furiously away from the herdsmen who were guarding them, and in spite of their utmost efforts, ran at full speed directly with the wind for fifty miles before they stopped. Three of the herdsmen followed them as far as they were able, but soon became exhausted, bewildered, and lost on the prairie. One of them succeeded in finding his way back to camp in a state of great prostration and suffering. One of the others was found frozen to death in the snow, and the third was discovered crawling about upon his hands and knees in a state of temporary delirium, after the tempest subsided. This terrific storm exceeded in violence and duration anything of the kind our eldest mountaineer had ever beheld. It continued with uninterrupted fury for sixty consecutive hours and during this time it was impossible to move for any distance facing the wind and snow. One of our employes who went out about two hundred yards from the camp, set out to return, but was unable to do so and perished in the attempt. Several antelope were found frozen upon the prairie after the storm.... At the termination of this frightful tempest, there was about three feet of snow upon the ground, but the warm rays of the sun soon melted it, and after collecting together our stampeded animals, we again set forward for Utah and on the third day following, struck the South Platte at its confluence with Cherry Creek. There was at that time but one white man living within one hundred and fifty miles of the place, and he was an Indian trader named Jack Audeby, on the Arkansas.
