Islais Creek or Islais Creek Channel (previously known as Du Vrees Creek, Islais Channel and Islais Swamp) is a small creek in San Francisco, California. The name of the creek is derived from a Salinan Native American word "slay" or "islay", the name for the Prunus ilicifolia wild cherries.Around the time of the Gold Rush, the area became an industrial hub, and the condition of the creek worsened. After the devastating 1906 San Francisco earthquake, the city decided to reclaim the creek using earthquake debris, reducing the waterbody to its present size. Though much of Islais Creek has been converted to an underground culvert, remnants still exist today at both Glen Canyon Park and Third Street. Several community organizations are dedicated to preserve these remnants, as they are important
