Great Salt Lake bioherms


Geologist Mike Vanden Berg of the Utah Geological Survey investigates Great Salt Lake’s microbialites. These domed structures cover about 386 square miles, or nearly 23 percent of the lake’s bed, and offer a glimpse of what the Earth was like for its first 3 billion years.

In a video, Bonnie Baxter, a biologist with Utah’s Westminster College, explains how cyanobacteria form microbialites and their imporant role in the lake’s ecosystem. The Natural History Museum of Utah will incorporate a specimen into a new exhibit. —Brian Maffly, Salt Lake Tribune
