Caldwell's Story: A Look Back

The area where Caldwell is today was once a natural pathway. It connected different parts of the Pacific Northwest. Long ago, Native American tribes would gather here. They came from many places to trade goods near the Boise River.

Later, explorers and traders from Europe and even Hawaii followed these paths. Then, pioneers traveled the Oregon Trail. They hoped for a better life in the Oregon Territory. These early travelers crossed the Boise River near where the Silver Bridge is now.

During the American Civil War, gold was found in Idaho's mountains. This brought many new people to the area. Some did not reach the mines. Instead, they settled along the Boise River. They started businesses like ferries and freight services. These early settlers also created small farms.

Caldwell began because of the Oregon Short Line Railroad. This railroad was built to connect Wyoming to Oregon through Idaho. In 1883, Robert E. Strahorn chose the spot for Caldwell. He picked a flat area of land, and the city was planned. Caldwell was named after Alexander Caldwell. He was a business partner of Strahorn and a former Senator from Kansas.

When Caldwell was planned in August 1883, people were encouraged to move there. In just four months, Caldwell grew very fast. It had 600 residents and 40 businesses. It also had a school and two newspapers. On January 15, 1890, Caldwell officially became a city.

The College of Idaho was started in Caldwell in 1891. It is still an important part of the city today. In 1892, Caldwell became the county seat of Canyon County. Many irrigation canals were built. These helped farming become a big part of Caldwell's economy. The Oregon Short Line Railroad became part of the Union Pacific Railroad. In 1906, a new train station was built. Caldwell continued to grow as a center for farming, shopping, and education.

In 2009, Caldwell finished a big project. They cleaned up and restored Indian Creek. This creek runs through downtown Caldwell. It had been covered up and used for waste. Now, the restored creek has bridges, walkways, and picnic areas.
