Historic Long Valley
In the early 1860’s Mormon Pioneers came into upper Long Valley and established Berrysville, but abandoned the settlement in 1866, when Indians forced them out during the Black Hawk War. The area remained under Indian control until 1871, when a second contingent of Mormon Pioneers came under the leadership of Bishop James Leithead. The new settlers re-named the spot “Glendale” after Leithead’s home in Scotland.
Historic Long Valley was the location of the most famous attempt at communal living in the west. Under Brigham Young’s leadership, the church of Jesus Christ of Latter-day Saints sponsored the “United Order of Zion.” Beginning in 1874 and centering at Orderville, several hundred people were involved.
