The Geology of Dagger Mountain at huge twist national park - Term Paper Example A few cretaceous sedimentary rocks are available and they incorporate buda, boquillas, Santa Clause Elena, and del rio. The site additionally comprises of two issues which incorporate the bowl and range high blessed messenger flaw and Laramide push issue which make a graben. The Dagger Mountain has a rise of 4173 feet and 1300 feet of alleviation. The anticline of the mountain is inclining at north-northwest inside the Sierra del Carmen. There are various opposite issues and creases. They are situated on the eastern side of cordilleran orogen.
