Bear Lake
While it is one of the oldest lakes in North America, Bear Lake is best known for its blue splendor. The water in Bear Lake is pristine, deep, and calcium-carbonate rich, giving it a blue appearance. Bear Lake, Rich County, Utah Photographer: Nikki Simon; © 2015

Microbialites

Microbialites

Microbialites take several forms: thinly layered (stromatolites), clotted (thrombolites), spherical (oncolites), and precipitated from mineral-rich springs (tufa or travertine). Stromatolites are currently growing on the gently sloping floor of Great Salt Lake at shallow water depths where the blue-green algae receives sufficient sunlight for photosynthesis.
