1. In 1856, the Mormon pioneers in Utah faced a severe winter, known as the "Mormon Handcart Disaster." On February 22 of that year, three rescue teams left Salt Lake City to provide aid and supplies to the stranded and starving pioneers. The rescue efforts saved the lives of hundreds, but many died from exposure, starvation, and exhaustion.

2. In 1819, fur trappers working for the Rocky Mountain Fur Company discovered a hot spring near what is now the city of Ogden. The hot spring, which later became known as the "Hot Sulphur Springs," became a popular destination for pioneers traveling west on the Oregon Trail.

3. On February 22, 1859, the Utah Territorial Legislature passed a law prohibiting polygamy, after years of pressure from the federal government. The law was largely ignored by the Mormons and was largely seen as a symbolic gesture.

4. In 1896, Utah became the 45th state in the United States. The state was founded by Mormon pioneers in 1847 and had been a territory for nearly 50 years before achieving statehood.

5. On February 22, 2002, the 2002 Winter Olympics opened in Salt Lake City, Utah. The Olympics were notable for being held just months after the September 11 attacks, and for controversies surrounding the selection and planning of the games. Despite these challenges, the Salt Lake City Olympics were widely regarded as a success.
