So are we which is why we keep going back. A one point in the history of North America, the middle third of the US was under water. The moving shores of the Western Interior Seaway provide "highways" for movements of during the dinosaur era. The unique geology and ecology of places like the badlands, arose as the sea way receded followed by the uplift of the Rocky mountain chain, ice ages, etc. The high desert and prairie grasslands are results of sedimentation as this sea dried. Each layer of rock had varying hardness and the bones of prehistoric plants and animals captured within leaving large cashes of fossilized remains. Also one will find areas of fossilized tracks of varying sizes of dinosaurs scattered throughout this area.
In the early 20th century a researcher found an area of about 80 acres that produced over 350 tons on dinosaur fossils that became one of the most significant paleontological finds of the 20th Century in the corner of NW Colorado. Today Dinosaur National Monument cover over 200 thousand acres in Northeast Utah, Northwest Colorado. The Alberta and Dakota badlands were from as the softer "mud rock" was eroded away leaving a layering of sandstone and rocks of varying hardness.
