Why did the mormons under the leadership of brigham young migrate west to utah? the great salt lake provided them with plentiful access to fresh water. they were welcomed by the local indians to settle there. they were searching for an isolated place where they could ensure security and survival. they desired to purchase inexpensive and fertile farmlands?

They were searching for an isolated place where they could ensure their security and survival. After the murder of their founder and prophet Joseph Smith and the religious discrimination they have suffered, the Mormons knew they have to leave their old place where they were settling. Under the leadership of Brigham Young, the Mormons ventured to west and found the Great Salt Lake Valley in Utah. Seeing that the place was isolated and wild, they immediately built a dam and planted turnips and potatoes and sent a word to their fellow Mormons about the land they have found and claimed.

The correct answer is third statement. Mormons (Church of Jesus Christ), under the leadership of Brigham Young, migrate west to Utah in July 1847. searching for an isolated place where they could ensure security and survival. Mormons moved west to escape religious discrimination and secure their lives after the murder of their founder and Prophet Joseph Smith in Illinois. The 24th of July is now celebrated as "Pioneer day" by Mormons to celebrate the day when they found their "Promised Land".
