The spring is approximately 250 by 300 feet (75 by 91 m) in size.

During summertime the chlorophyll content of the organisms is low and thus the mats appear orange, red, or yellow. However during the winter, the mats are usually dark green, because sunlight is more scarce and the <a href="https://en.wikipedia.org/wiki/microbes" class="extiw" title="w:microbes">microbes</a> produce more chlorophyll to compensate, thereby masking the carotenoid colors. |
