Whirligig Geyser


Whirligig was so named because while erupting its water swirls in its crater while its rhythmic sound can be heard around the basin. The orange-yellow iron oxide deposits around Little Whirligig make it one of the most colorful features in Porcelain Basin. In the summer of 2000, it became dramatically more acidic, allowing green-colored Cyanidium alga to grow around its rim. It has been dormant for several years.
