LAS VEGAS - Authorities in Las Vegas are puzzled over the mysterious monolith that was spotted over the weekend near Gass Peak.
The Las Vegas Metro Search and Rescue said they'll leave it up to the internet to figure out how the object got there.
"We see a lot of weird things when people go hiking like not being prepared for the weather, not bringing enough water... but check this out!" authorities posted on its Facebook page.
Similar monoliths also have been found in Belgium, Romania and the Isle of Wight – an island in the English Channel.

In November 2020, one of the monoliths, estimated at between 10 feet and 12 feet high, was found by Utah state wildlife employees who were counting sheep from a helicopter.

FOX Weather's summer outlook for 2024
Meteorological summer starts on June 1.
In the meantime, authorities are reminding people how to stay cool as temperatures rise such as bringing plenty of food and water.
The first significant heat wave of the summer is underway and has tens of millions of people from the Midwest to the Northeast looking for ways to stay cool as temperatures soar into the mid-to-upper 90s this week.
The sweltering temperatures are the result of a massive ridge of high pressure that parked itself over the eastern U.S., and while temperatures in major cities like Chicago, Washington, D.C., New York City and Boston will get into the 90s, the humidity will make it feel even hotter with feels-like temperatures soaring above 100 degrees.
