You Can Now Walk to Tower Rock in the Middle of the Mississippi River [PHOTOS]

In Perry County, Missouri, about 100 miles south of St. Louis, you can now walk to a gigantic rock in the middle of the Mississippi River.

This rock, known as Tower Rock, is usually surrounded by water. Visitors can admire it from the shore or take a boat to see it. But now, with water levels dropping to an all-time low, visitors can walk across the river to see Tower Rock up close. Some have even tried to climb Tower Rock.

"When the Mississippi River Chester Gauge is less than 1.5 feet it is possible to walk out to Tower Rock," the Missouri Department of Conservation's website says.

CNN reports that drought is now affecting 55 percent of the United States –– including Missouri, with 40 percent of the state experiencing severe drought.

This has led to lowered water in the Mississippi. On Thursday, water levels fell to nearly zero at the Mississippi River Chester Gauge –– a near-all-time low –– allowing a walkway to emerge leading to Tower Rock.

Bailey White is a Tennessee resident, where water levels in the Mississippi have also dipped. She told CNN that this is the least water she has ever witnessed in the river.

“I've seen the water levels drop a little, and I've seen them super high, but I've never seen them this low before," White said. "We couldn't even get our small boat on the river. We had to try five different docks until we were able to do so. It's a small boat, so it doesn't sit deep in the water, but we definitely had to pay extra attention a few times, or we would've hit some sand.”

Over the weekend, people flocked to Tower Rock, flooding social media with pictures. Here is a look at what they saw.
