It is an urban park named by the Musqueam, Squamish and Tsleil-Waututh Nations. This is the first park in Vancouver to be gifted a name by the Musqueam, Squamish and Tsleil-Waututh Nations. sθәqәlxenәm ts'exwts'áxwi7, meaning 'rainbow', was chosen for this place because the land where the park now sits was once forested with large trees and had many sources of water, including a marsh where the sun and mist would form rainbows.
