Magic Valley
The Magic Valley is an area in south-central Idaho composed of eight counties. Glenns Ferry, although not in one of those counties, is sometimes grouped with the Magic Valley as well, as it is just outside the boundaries of Gooding County.
The northern part of Blaine County is referred to as the Wood River Valley, though it is in the Magic Valley. The towns of Ketchum, Sun Valley, Hailey, and Bellevue compose the Wood River Valley.
Members of the LDS Church immigrated to what is now the Magic Valley in the 1880s. Specifically, they immigrated to today's Minidoka and Cassia County. The Cassia area consists of the towns of Burley, Rupert, Paul, and Oakley, among others.
Twin Falls is the largest economic center of the region. It was founded in 1904. Towns in neighboring counties came about in the following years. With the advent of water power and electricity, the farming industry grew, thanks to modern farming methods and modern irrigation. The growth of farming led to a growth in industries that farms support, and banks and schools and other city essentials followed suit.
Members of the Church of Jesus Christ of Latter-day Saints (Mormon Church) make up roughly half of the Magic Valley. Approximately 25 percent of Twin Falls County, and upwards of 60 to 70 percent in the eastern Magic Valley, is LDS.
There are four stakes in Twin Falls County, one in Jerome County, and one in Gooding County (which covers Camas County as well). Another stake covers Lincoln and Blaine County. Five stakes cover Cassia County and two cover Minidoka County.
Early in his life, Apostle Dallin H. Oaks lived in Twin Falls, until his father's death and his mother's immediate need to get an education made a move necessary. His brother, Merrill, who served in the Second Quorum of the Seventy was born in Twin Falls. Another apostle, David B. Haight grew up in Oakley and a number of his family remained there (although he, himself, lived elsewhere as an adult). Indeed, Haight's grandfather was a pioneer to the Oakley Valley. D. Rex Gerratt, a Burley dairy farmer, is a member of the Second Quorum of the Seventy.
The Sun Valley branch, since it is situated around a resort, has hosted General Authorities and general auxiliary officers. Prophets in that area for non-church reasons have been speakers in that area, too.
Due to the area's high membership, Church President Gordon B Hinckley announced a temple to be built in Twin Falls in the October 2004 General Conference. It should be completed in late 2007 or early 2008.
