If you look at Google Earth, you can see the potash ponds in Moab appearing in purples and pinks. There are a few places to go to see the potash ponds in Moab, but some are better than others.
The bright blue ponds are actually potash evaporation ponds owned by Intrepid Potash, Inc.
The potash ponds are blue because of the blue dye they add to the brine. This dye helps speed up evaporation as it increases the absorption of sunlight.
We visited in late May, and most of the ponds were still a bright blue color.
The potash ponds are located between Arches National Park and Dead Horse Point State Park and Canyonlands State Park near the Colorado River.
You can see the potash ponds from Dead Horse Point State Park. If you are going to head to Dead Horse for sunset or to view the canyon from there.
To get to this point in Google Maps, you can put in Elvis Rock. Stop for a quick photo and then continue past Elvis Rock to see the potash ponds.
