Oskaloosa is a city in Iowa. It is the main town, or county seat, of Mahaska County, Iowa. Long ago, in the late 1800s and early 1900s, Oskaloosa was a very important place for mining bituminous coal. In 2020, about 11,558 people lived there.

Oskaloosa gets its name from Ouscaloosa. She was a Creek princess who married Seminole chief Osceola. Some people used to think her name meant "last of the beautiful." However, in the Mvskoke-Creek language, "Oskaloosa" actually means "black rain." This comes from the words "oske" (rain) and "lvste" (black).

The first European-American settlers arrived in 1835. They were led by Nathan Boone, the youngest son of the famous frontiersman Daniel Boone. They chose this spot for the first Fort Des Moines. It was on a high ridge between the Skunk and Des Moines rivers. This ridge was first called the Narrows.

The town was officially planned in 1844. That's when William Canfield moved his trading post to Oskaloosa. The state government also chose Oskaloosa to be the county seat that same year.

Railroads and Growth

Railroads helped Oskaloosa grow. The Des Moines Valley Railroad arrived in 1864. Later, other railroads like the Central Iowa Railway and the Burlington and Western Railway also came to town. These railways made it easier to transport goods and people.

On January 6, 1882, a big explosion happened. It severely damaged many buildings in Oskaloosa. Most of the glass windows in the area were broken. Sadly, three boys died in the explosion. They had been seen shooting at a gunpowder storage building outside of town.

Coal Mining in Oskaloosa

The first bituminous coal mine in the area opened around 1853. Robert Seevers started it by digging into a coalbed near a creek. At first, people only mined coal for local use. But once the railroads arrived, coal from Oskaloosa was shipped far away.

By the 1880s, over one million tons of coal were mined in the county from 38 mines. In 1887, there were 11 coal mines in or near Oskaloosa. By 1895, Mahaska County produced more coal than any other county in Iowa. Coal mining was the main industry in the region in 1911.

Several large coal-mining towns were near Oskaloosa. Muchakinock was about five miles south of town. Lost Creek was another company town with about 500 people in 1905.

On January 24, 1902, there was a mine explosion at Lost Creek No. 2 mine. A miner accidentally caused a coal dust explosion. This set off barrels of gunpowder stored in the mine. Twenty men died, and 14 more were badly hurt. This event led to a statewide miners' strike. Because of this, a new law was made in 1903 to control blasting in coal mines.

Oskaloosa covers about 7.45 square miles (19.3 square kilometers). Most of this area is land, with a small amount of water.
