The material on the mountains was not always up there. Mountains are generally created by what is called uplift. And places that were under water and then had remains laid down and fossilized can be uplifted through long periods of time to create mountains. The fossils are then found up there in the mountains. The geologic process is fairly well understood and modeled by geologists.
