About 100 million years ago, the sea reached the Mesa Verde area and deposit ed the Dakota Sandstone. Initi ally, sand was deposited in a very shallow area of the sea near the beach. The sand was compacted and cemented into sandstone. These rocks form the erosion resistant base of the Montezuma Valley below Mesa Verde, …Sandstone is one of the common types of sedimentary rocks that form from sediments. There are many other types. Sediments may include: ... Sediments are deposited on beaches and deserts, at the bottom of oceans, and in lakes, ponds, rivers, marshes, and swamps. Avalanches drop large piles of sediment.
