In late October 2019, unique mineral mounds began forming on the south shore of Great Salt Lake. They are not composed of common table salt but mirabilite from underground springs. When the sodium-sulfate-rich spring water hits the cold winter air, mirabilite crystals form and build up a collection of small circular terraces. Spring-fed crystalline mirabilite mounds are rare; they have never before been scientifically documented at Great Salt Lake.

This work of art was exhibited in the Circles of Influence exhibition in the Salt Lake City Library, Salt Lake City, UT June 24 - August 4, 2023.
