Ghost Plume Beneath Oman May Have Moved India

Jan Otte

An ancient geological force has been quietly shaping the planet for millions of years deep beneath Oman’s rough terrain. Scientists have found a “ghost” plume, a column of hot rock rising from the Earth’s core. This plume may have been very important in changing the direction of the Indian tectonic plate when it crashed into ...

Scientists Uncover Secret History of Hells Canyon

Jan Otte

Hells Canyon, a winding cut through the American West, has kept its origins a geological mystery for hundreds of years. Scientists have been trying to figure out how this 1.5-mile-deep (2.4 km) chasm, carved by the Snake River, came to be for a long time. It runs through Oregon, Idaho, and Washington. How could the ...

Deeper Than the Grand Canyon But Only 2 Million Years Old? Meet Hells Canyon

Suhail Ahmed

While the Grand Canyon’s 1.7-billion-year-old rock layers and 6-million-year-old chasm have long dominated America’s geological imagination, a far deeper and dramatically younger gorge has been hiding in plain sight. Hells Canyon, slicing 2,400 meters (7,900 feet) into the Idaho-Oregon border, is North America’s deepest river gorge, yet a groundbreaking study reveals it was carved in ...

They first thought of deep geological forces, maybe a plume of molten rock lifting the ground from beneath. New studies, however, point to a rather more unexpected offender: drought. The very ground under South Africa is rebounding like a ...
