History

Prior to European colonization, the Grand Mound Prairie was home to the Upper Chehalis (q̓ʷay̓áyiɬq̓) people. A large settlement called aqáygt (meaning "long prairie" in the Upper Chehalis language) was located where Grand Mound is today, but settlers burned and razed it after a smallpox outbreak caused by contact with Europeans killed hundreds of indigenous people in the area.

Grand Mound was founded in 1851, with stage service arriving in 1854. Known as Mound Prairie, the community built Fort Henness, which consisted of two blockhouses, in 1855 amid fears over potential Native American attacks during the Puget Sound War, despite the Upper Chehalis abstaining from the conflict. The fort housed 224 people, including Company F of the First Regiment of Washington Territorial Volunteers under the command of Captain Benjamin Lee Henness. The fort never experienced combat. In 1913, the Washington State School for Girls (also known as the State Training School for Girls) was created and opened on 70 acres (28 ha) in 1914. The school was renamed as Maple Lane School in 1959, and closed in 2011.
