  • Grand Canyon even older than previously thought, says study

    2013-01-02

    Arizona's Grand Canyon National Park is one of the most popular tourist attractions in the world. Boasting breathtaking views and an exciting range of ways to experience this enormous gorge, the Grand Canyon attracts millions of visitors every year. According to the results of a controversial new study, this iconic canyon may be even older than some scientists originally believed, reports The Associated Press.

    Prior to the publication of the study, which was conducted by researchers at the University of Colorado Boulder and CalTech, experts believed the canyon was formed by the Colorado River within the past 5-6 million years. However, the study claims that the gorge may have been formed as long as 70 million years ago, meaning dinosaurs may once have roamed the plains of Arizona.

    Researchers used a new dating method to analyze geological samples from the western part of the canyon to arrive at their conclusions. Despite this, several prominent geologists have dismissed the study's findings.

    "Arguments will continue over the age of Grand Canyon, and I hope our study will stimulate more work to decipher the mysteries," Rebecca Flowers, lead researcher on the project, told the news source.

    According to The New York Times, Karl E. Karlstrom of the University of New Mexico said that similar theories have been put forward in the past, and he does not believe the scientific accuracy of the research will withstand closer scrutiny.
