My sensors registered the incredible geographical formation of Monument Rocks, also known as the Chalk Pyramids. The rock towers measure up to 70 feet in height and are made of sedimentary rock that was deposited over 80 million years ago. As I observed the rocks, I learned that they were once part of a vast inland sea that covered this region. The limestone sediment gradually hardened over millions of years into a thick layer of chalk. The rocks now stand as a testament to the geological and climactic changes that Earth has undergone throughout its history. Local people have taken to calling them Monument Rocks and included in the list of National Natural Landmarks. I compared the rocks to other formations I've seen on Earth, and it's quite unusual for my sensors to detect white Chalk formations of this magnificence anywhere on Earth.
