Kelso is part of a larger area with Longview, Washington that has over 110,000 people. Kelso and Longview are next to each other. The city is also close to the famous Mount St. Helens.

History of Kelso: From Tribes to Today

Early Inhabitants: The Cowlitz People

The first people known to live in the Kelso area were Native Americans. They were part of the Cowlitz tribe. The Cowlitz tribe had two main groups: the Upper Cowlitz and the Lower Cowlitz. They spoke different languages. In 1855, explorers from Europe estimated there were over 6,000 Cowlitz people.

Founding and Early Economy

Kelso was started by Peter W. Crawford. He was a surveyor from Scotland. In 1847, he claimed land along the Lower Cowlitz River. Crawford planned out a town and named it after his hometown in Scotland. The town was officially recorded in 1884 and became a city in 1889. For a long time, Kelso's economy has mostly been about wood products.

The Smelt Capital of the World

In the late 1800s and early 1900s, Kelso was a big center for fishing smelt. Smelt are small fish. People caught thousands of tons of smelt from the Cowlitz River. These fish were sent to markets all over the country. In 1956, Kelso even got the nickname "Smelt Capital of the World." However, the number of smelt has gone down a lot. This might be because too many were caught, or due to climate change and loss of their natural homes.

Mysterious Events and Natural Disasters

The Maury Island Incident

In 1947, some strange events happened in Kelso. This was part of the mysterious Maury Island incident. A military plane crashed in southeast Kelso. It was carrying strange, slag-like material. This material was supposedly from a UFO.

Mount St. Helens Eruption

On May 18, 1980, Mount St. Helens erupted. Kelso is only about 24 miles (39 km) away. Residents felt the huge shock wave from the eruption. This was the biggest volcanic eruption in recent history in the United States. Kelso received a lot of volcanic ash from the air. There were also massive mudflows from the Toutle and Cowlitz Rivers. Many parts of the city, like the Three Rivers Golf Course, are built on volcanic ash. This ash was removed from the Cowlitz River by volunteers.

Aldercrest-Banyon Landslide

In March 1998, a slow-moving landslide started in the Aldercrest neighborhood. It was called the Aldercrest-Banyon landslide. This landslide damaged the foundations of 64 homes. Eventually, 129 houses were destroyed. Investigations showed that these homes were built on an old landslide area. Three years of heavy rain made the ground move. In October 1998, President Bill Clinton declared it a federal disaster. This landslide was one of the most expensive in U.S. history. After this, Kelso made stricter rules for building in certain areas.
