LDS settlement of Emery County: the call to colonize Castle Valley, founding of pioneer towns, cooperative irrigation, and the transformation of a remote desert into an agricultural community.
Coal, Copper & Uranium
The extractive century: coal seams of the Wasatch Plateau, uranium-rich sandstones of the San Rafael Swell, copper byproducts, company towns, the Wilberg and Crandall Canyon disasters, and the ongoing energy transition reshaping Emery County’s economy.
Rails, Roads & Infrastructure

Arts, Literature & Media
Emery County's cultural footprint runs unusually deep for a county of fewer than 10,000 residents: pioneer brass bands and Welsh choral traditions; coal-camp music carried in by Greek, Italian, and Slavic miners; a 118-year-old county newspaper; the Emery Telcom/ETV broadcasting cooperative; the Castle Valley Pageant performed every other summer for nearly half a century; a four-museum circuit; folk-craft guilds; and a San Rafael Swell that has doubled as a Hollywood backdrop.
