The object of the Mormons was to find a place where they might be free to live according to their own beliefs. So far they had been continually hunting for what they called their own City of Zion. As they spent that winter of 1846-47 in their camp near Council Bluffs, they tried to decide where they would be safest from persecution. The far west had few settlements as yet, and they were free to take what land they would, but the Mormons wanted a site on which to lay the foundations of a city that should one day be rich and prosperous. They decided to send out a party of explorers, and in April, 1847, one hundred and forty-three men, under command of Brigham Young, with seventy-three wagons filled with food and farm tools, left the headquarters to go still farther west. They journeyed up the north fork of the Platte River, and in the valleys found great herds of buffaloes, so many in number that they had to drive them away before the wagons could pass. Each day the bugle woke the camp about five o'clock in the morning. At seven the journey began. The wagons were driven two abreast by men armed with muskets. They were always prepared for attacks from Indians, but in the whole of their long journey no red men ever disturbed them. Each night the wagons were drawn up in a half-circle on the river bank, and the cattle driven into this shelter. At nine the bugle sent them all to bed. So they made their way over the Uinta range to Emigration Canyon. Down this canyon they moved, and presently came to a terrace from which they saw wide plains, watered by broad rivers, and ahead a great lake filled with little islands. Three days later the company camped on the plain by the bank of one of the streams, and decided that this should be the site of their new city. They held a meeting at which they dedicated the land with religious ceremonies, and at once set to work to lay off fields and start plowing and planting. Some of them visited the lake, which they called the Great Salt Lake, and bathed in its buoyant waters. Day by day more of the pioneers arrived, and by the end of August they had chosen the site of their great temple, built log cabins and adobe huts, and christened the place the "City of the Great Salt Lake." This name was later changed to Salt Lake City.
