Henry Mountains

               The Henry Mountains are located in Southeastern Utah in the middle of the Colorado Plateau.  They were formed by several layers of laccoliths forming on each other.  A laccolith is an igneous intrusion that causes a dome uprising in the layers of crust above the location of the intrusion. When these intrusions occur the magma spreads through cracks in the surrounding rock and then cool raising the layers above them so they are slightly sloped.  Several layers of laccoliths on top of each other they form what is called a Christmas tree laccolith.  The Henry mountains have various areas where the rocks are angled upwards which is a sign of the laccoliths that formed the mountain range.
