Recent research reveals that Hells Canyon, the U.S.'s deepest river gorge, was formed approximately 2.1 million years ago through the overflow of a giant lake, influenced by a shifting Idaho landscape. The study involved examining ancient river sediments located within caves that are now high above the Snake River, uncovering how the canyon was created. Experts emphasize this work's significance, highlighting its potential to enrich understanding of Earth's natural history and the processes that shape majestic landscapes, despite Hells Canyon being less studied compared to the Grand Canyon.
Hells Canyon, the deepest river gorge in the U.S., was rapidly carved 2.1 million years ago when a giant lake overflowed due to a shifting landscape.
This brilliant study used ancient river sediments hidden in caves to date the enigmatic Hells Canyon, shedding light on its geological history.
Matthew Morriss emphasizes the importance of understanding landscapes like Hells Canyon for appreciating their natural history and the forces that shaped them.
Despite Hells Canyon's greater depth compared to the Grand Canyon, it has not garnered as much scientific attention, making this research particularly significant.
