Coming across this... I have no idea what you call it.. was a complete surprise. We were driving down the freeway looking for the Bonneville Salt Flats, which is massive by the way, and we saw this super vibrantly colored body of water and had to turn around and head towards it. It's pretty easy to miss if you're not staring dead out the window the entire drive. It's actually dipped into the ground with about 2-3 feet of mounds surrounding it. I really wanted to jump into it but the lack of knowledge to as what this water was made out of, I decided that it was a smart decision not to. I could've came out with superhero powers, could've... But I guess I will never know.
