The Changing Workplace
The 20th century ushered in a change from handcrafting to machine tooling. Henry Ford introduced one of the first moving assembly lines as a way to turn out more cars more quickly, and the emerging auto industry popularized this mode. A photo of the Doble Steam Motors Corporation factory shows a line of workers and car chassis in production. This new technology, and the spread of industrialization, changed forever the way that work was completed. A wide variety of industries all across the count

Change in the Mountains
The Appalachian Mountains of western North Carolina rise abruptly from the Piedmont, the state's central plateau, and include the ranges of the Balsam, Black, Blue Ridge, Great Smoky, and Nantahala Mountains. The region is home to several of the highest peaks east of the Mississippi River. The rugged geography of these mountains delayed the arrival of European settlers to the area, slowed the pace of development, and for many years preserved a distinct regional culture.
