History
In 1862 ranchers came to Long Valley, land east of the future Zion National Park, to graze cattle along the East Fork of the Virgin River. Robert and Isabella Berry named the area "Berryville". In 1866 after the Berrys were killed by Indians, the other settlers left. In 1871 Mormons from the Muddy River settlement in Nevada came to settle, naming their town "Glendale". The people of St. Thomas, Nevada, relocated en masse to Glendale in that year, preserving their old ward organization in the new location. By the late 1800s the Mormon communities in the area had grown in the nearby towns of Orderville and Mt Carmel Junction, and Glendale became part of the United Order, a program of economic and moral reform that began in 1874 under Brigham Young. On March 29, 1935, Glendale became an incorporated town. The towns of Mount Carmel, Orderville, and Glendale are known as Long Valley.
