Rocks 70 Million Years Old

no one knows exactly how old the #grandcanyon is. 👴🏻 a study suggests that the process may have started as far back as 70 million years ago! 🪨 the grand canyon was not as breath-taking as we imagined since we visited it last, but we still took a million photos of the same view. 📸 on the way back, we saw the night view of the #hooverdam which was pretty cool. 🦫
