Researchers connected another Arizona geographical feature, the Meteor Crater to the Grand Canyon’s formation.
The Meteor Crater, located about 130 miles southeast of the Grand Canyon’s South Rim, was formed more than 56,000 years ago by a large iron-nickel asteroid.
The study hypothesizes that the impact triggered landslides in the Grand Canyon that accounted for a hefty portion of its shaping.
These landslides supposedly blocked off the Colorado River and formed a ‘paleolake,’ which is ancient lake that no longer exists, in the canyon.
Ultimately, researchers deemed that since all of these timelines appear to match up, the asteroid that created the massive crater also caused the landslide.
The landslide led to the paleolake, which created a dam in the Colorado River.
This dam allowed for water to build up and eventually cause surging floods that flooded caves in the canyon, causing further erosion.
This theory makes good sense and accounts for all of the evidence, including ancient driftwood in caves at very high elevations within the canyon. ABN
