Two unknown people destroyed an ancient rock formation in Lake Mead National Recreation Area in Nevada, USA, in just a few seconds. A video showing the two men in the act has been circulating on X (formerly Twitter) since the beginning of April. The national park authorities have therefore initiated an investigation and are asking the public to help find the perpetrators.

A video posted to social media this month captured two men destroying ancient rock formations at Lake Mead National Recreation Area in Nevada. National park rangers are asking for the public’s help in identifying the visitors, who could face federal charges for vandalizing protected land.

The record-breaking rain soaking the Southwest U.S. in recent weeks still won't be enough to eliminate the megadrought status in the notoriously arid region completely, according to researchers.

Summer monsoons in the Southwest are difficult to forecast with total accuracy, but the future of the temperamental rainstorms under climate change is an even bigger mystery.

Scientists are studying mineral deposits in the caves of the Grand Canyon to understand the impacts of climate change.

They chose an ancient calcium projection, called stalagmite, from the floor of an undisturbed Grand Canyon cave and studied its geochemistry. The research team was led by the University of Nevada, Las Vegas, and included the University of New Mexico.

The Grand Canyon, known for its majestic valleys and millennia-old rock layers, has now unveiled another marvel — its extensive cave systems that could potentially unlock secrets about climate change.
