“Having successfully brought the first company of Saints across the plains to Utah, President Brigham Young now turned his attention to establishing God’s kingdom in the desert. Through his vision and leadership, what was once an empty desert became a thriving civilization and a haven for the Saints. His plainspoken direction helped the Saints imagine the possibilities of their new home and led them forward in their quest to build God’s kingdom.
“Two days after the first company’s arrival, Brigham Young and several of the Twelve climbed a round bluff on the mountainside that President Young had seen in vision before leaving Nauvoo. They looked out over the valley’s vast expanse and prophesied that all nations of the world would be welcome in this place and that here the Saints would enjoy prosperity and peace. They named the hill Ensign Peak after the scripture in Isaiah that promised, ‘He shall set up an ensign for the nations, and shall assemble the outcasts of Israel’ (Isaiah 11:12).”

Isaiah 11:12
12 And he shall set up an ensign for the nations, and shall assemble the outcasts of Israel, and gather together the dispersed of Judah from the four corners of the earth.
President George A. Smith said:
“We look around today and behold our city clothed with verdure and beautified with trees and flowers, with streams of water running in almost every direction, and the question is frequently asked, ‘How did you ever find this place?’ I answer, we were led to it by the inspiration of God. After the death of Joseph Smith, when it seemed as if every trouble and calamity had come upon the Saints, Brigham Young, who was President of the Twelve, then the presiding Quorum of the Church, sought the Lord to know what they should do, and where they should lead the people for safety, and while they were fasting and praying daily on this subject, President Young had a vision of Joseph Smith, who showed him the mountain that we now call Ensign Peak, immediately north of Salt Lake City, and there was an ensign [that] fell upon that peak, and Joseph said, ‘Build under the point where the colors fall and you will prosper and have peace.’ The pioneers had no pilot or guide, none among then had ever been in the country or knew anything about it. However, they traveled under the direction of President Young until they reached this valley. When they entered it President Young pointed to that peak, and said he, ‘I want to go there.’ He went up to the point and said, ‘This is Ensign Peak. Now, brethren, organize your exploring parties . . . ; go and explore where you will, and you will come back every time and say this is the best place.’ They accordingly started out exploring companies and visited what we now call Cache, Malad, Tooele, and Utah valleys, and other parts of the country in various directions, but all came back and declared this was the best spot.
“I have traveled somewhat extensively in the Territory, and I bear my testimony this day, that this is the spot, and I feel confident that the God of Heaven by His inspiration led our prophet right here. And it is the blessing of God upon the untiring energy and industry of the people that has made this once barren and sterile spot what it is today.”
