About Columbia County
Columbia County Timeline
Columbia County, Oregon has a rich history that dates back thousands of years. Native American tribes, including the Chinook and Clatskanie tribes, inhabited the region for centuries before European settlement. In the early 19th century, explorers and fur traders, such as Lewis and Clark, ventured into the area, marking the beginning of the region's interaction with European settlers.
In the mid-19th century, Columbia County experienced a significant influx of settlers, drawn by the prospects of fertile land and natural resources. The establishment of the Oregon Trail and the completion of the Columbia River Highway in the late 1800s further encouraged the growth of Columbia County. The county went through several name changes before settling on its current name in 1854, reflecting its position along the Columbia River.
The late 19th century saw the rise of industries such as logging, fishing, and coal mining. The timber industry, in particular, played a crucial role in shaping the county's economy and identity. The Oregon-American Lumber Company, headquartered in Rainier, became one of the largest lumber producers in the world at the time.
With the decline of the timber industry in the latter half of the 20th century, Columbia County has sought to diversify its economy. Today, the county boasts a mix of industries, including manufacturing, agriculture, and tourism. The natural beauty of the region, with its lush forests, rivers, and scenic views, continues to attract visitors and residents alike. Columbia County's rich history is celebrated through various museums, historical sites, and events that highlight the region's unique heritage.
