The spring air in the small, sand-dusted town has a soft haze to it, and clumps of green-gray sagebrush rustle in the breeze. Bluffdale sits in a bowl-shaped valley in the shadow of Utah’s Wasatch Range to the east and the Oquirrh Mountains to the west. It’s the heart of Mormon country, where religious pioneers first arrived more than 160 years ago. They came to escape the rest of the world, to understand the mysterious words sent down from their god as revealed on buried golden plates, and to practice what has become known as “the principle,” marriage to multiple wives.

 

Today Bluffdale is home to one of the nation’s largest sects of polygamists, the Apostolic United Brethren, with upwards of 9,000 members. The brethren’s complex includes a chapel, a school, a sports field, and an archive. Membership has doubled since 1978—and the number of plural marriages has tripled—so the sect has recently been looking for ways to purchase more land and expand throughout the town.
