Today I went to Devil's Backbone...BORING...So I'm going to tell you about stuff there are four layers they are Dakota, Entrada, Morrison, and Lykin. . It is made of sedimentary rock. It was made by erosion for millions of years earliest the jurassic period. Dakota is the top layer made of sand stone. Morrison is the next, many fossils are found in the Morrison layer. Then the Entrada this a very reddish area. The last one Lykin, is the lowest layer used for irragation and other things. That is all for now
