Garen of the Gods is a public park located in Colorado Springs. The outstanding geologic features of the park are the ancient sedimentary beds of red and white sandstones, conglomerates and limestone that were deposited horizontally, but have now been tilted vertically and faulted by the immense mountain building forces caused by the uplift of the Pikes Peak massif. Evidence of past ages; ancient seas, eroded remains of ancestral mountain ranges, alluvial fans, sandy beaches and great sand dune fields can be read in the rocks. A spectacular shear fault can be observed where the Tower of Babel (Lyons Sandstone) contacts the Fountain formation. The name Colorado is said to come from the color of the sandstone. There are many fossils to be seen: marine forms, plant fossils, and some dinosaur fossils.
