The view of potash ponds in the middle against red desert is amazing.
Bright blue ponds is actually a potassium carbonate evaporative pond owned by Intrepid Potash, Inc.
They have three carbonate mines in the western United States and potassium carbonate pond is best known in Moab, Utah.
Potash ponds is blue color because of blue dye that is added to salt water.
This dye increases absorption of sunlight which helps increase rate of evaporation.
Darker water absorbs more sunlight and heat so that potassium can be harvested faster and process can be restarted.
Potash ponds is not always bright blue. This process takes about 300 days and in the process, the pond becomes colorful.
You can see a bright blue color immediately after dye is added.
The pond turns brown color after almost all water evaporates, leaving potassium on the bottom of the pond for harvesting.
This harvested potassium carbonate is used to make glass, porcelain, soap, fertilizer, etc.
