The name "Issaquah" comes from a Native American word, /sqʷáxʷ/. It means things like "the sound of birds," "snake," or "little stream." The area was once called "Squak Valley," which also came from this same Native American name.

In September 1885, there was a sad event in the area. Some Chinese workers who came to pick hops were attacked. Three of them died.

The town was briefly called Gilman, named after Daniel Hunt Gilman, who brought railways to the area. But soon after, it went back to being called Issaquah.

The city officially became a city on April 29, 1892. It started as a small mining town, digging for coal in the nearby mountains. When the coal ran out, the town became a center for the lumber business. Companies would send timber from Issaquah to Seattle and other growing towns. After the Great Depression, the town became quieter.

Later in the 20th century, companies like Boeing provided many jobs. Then, Microsoft and other tech companies moved into nearby cities like Redmond and later to Issaquah itself. In 1996, Costco moved its main office to Issaquah from Kirkland.

Issaquah's Location and Landscape

Issaquah is about 15 miles (24 km) southeast of Seattle, near the south end of Lake Sammamish. Its neighbors are Bellevue to the west and Sammamish to the north. The city is part of the beautiful Mountains to Sound Greenway.

The city covers about 11.40 square miles (29.53 sq km). Most of this is land, with a small amount of water.

Issaquah is surrounded by three mountains, often called the Issaquah Alps: Cougar Mountain to the west, Squak Mountain to the south, and Tiger Mountain to the southeast. To the north is Lake Sammamish. Parts of these mountains have homes, but most of them are protected as parks, like Squak Mountain State Park and Cougar Mountain Regional Wildland Park. These mountains are different from the Cascade Range because they weren't formed by volcanoes. Scientists believe they are much older mountains that have worn down over time.

Issaquah's Climate

Issaquah has a climate with cool, very wet winters and warm, somewhat humid summers. Even though there isn't a completely dry season, winters get much more rain than summers.
