Why did the Mormons establish their church in the desert by the Great Salt Lake?

The Church of Jesus Christ of Latter-day Saints (the "Mormon" church) was founded in New York state in 1830, and church headquarters quickly moved to Ohio, then to Missouri and Illinois due to extreme persecution. Because the Mormons faced violence in the east, they moved to the desert near the Great Salt Lake to practice their religion in peace, arriving there in 1847.
