Little Whirligig got its name because of its close proximity to Whirligig Geyser. Whirligig was so named because its water swirls in its crater during eruptions. The orange-yellow iron oxide deposits around Little Whirligig make it one of the most colorful features in Porcelain Basin. It has been dormant for several years.
