Bear Lake

• Why is Bear Lake so blue? And other commonly asked questions (pdf)
  Public Information Series #96

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.

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.
