Colorado’s Front Range is the eastern most expression of the Rocky Mountains and is one of the features that make Colorado unique. The Front Range is a complex arrangement of meta-sedimentary and meta-volcanic rocks that have inspired geologists since the Hayden surveys of 1873 and 1877. The Front Range is studied today to help scientists test and understand concepts related to the Laramide Orogeny, which is the period of mountain building that started in the Late Cretaceous, the duration and cause of which are still in dispute. The Front Range is an economically important source of metals including gold, silver, uranium, molybdenum, and tungsten and industrial minerals such as clay and feldspar.
