Glendo Geology

            Like much of the plains of Wyoming, Glendo is made up of the Paleozoic and Mesozoic rocks that were carried by rivers to the area after being thrown from volcanic eruptions.  This area is different though because another event occurred here.  “Violent and prolonged volcanic eruptions in the Great Basin region of Nevada and eastern California” (Blackstone 113)  sent out volcanic ash that was carried by streams to finally settle as fine- grained sediment on the older Precambrian rock base.  Erosion from streams since then has revealed this history and has bared rocks from 30 million years ago.  There are also sand dunes that spread from this area into Nebraska.  The park has become a place of recreation with the Glendo Reservoir, the Sandy Beach, the North Platte River, and many campgrounds.
