Considering how large the Grand Canyon is, it's no surprise that this massive natural wonder is hiding a secret or two. While Arizona may be home to quite a few amazing hot springs, there's one pool of water that you're going to want to make a point to avoid dipping your toes into.
Hiding in plain sight along the Colorado River, there's a unique pool of water at the bottom of the Grand Canyon.
You can find this potentially deadly body of water at mile 212.9; it's accessible by boat along this area of the river,
Resembling a giant pumpkin that you would expect Cinderella to step out of, Pumpkin Spring Pool is actually a toxic wonder that you'll want to avoid.
While it may look like the perfect place for you to relax in the water while overlooking the beautiful river, you won't want to step foot in this spring. The limestone formation looks like an enormous pumpkin that was left along the side of the river, filled with murky green water that flows over the side of the spring.
This spring contains the most poisonous water in all of the Grand Canyon; soaking in it is highly advised against.
Wondering what exactly is in this water that makes it so potentially deadly? The water in this pumpkin-like spring is filled with copper, lead, zinc and frighteningly high levels of arsenic.
Small amounts of exposure to the water won't kill you, but this obviously shouldn't be your first choice when it comes to finding a place to soak in the sun. Drinking the water is prohibited, with recent testing showing that one liter of the water contains 1100 milligrams of arsenic. Yikes! While this isn't an ideal place for you to spend the day in the water, the pumpkin look-alike is beautiful to see and should still certainly be on your bucket list.
