Nearly 1.05 billion years ago, during the Precambrian period,hot magma pushed up from the Earth’s core and formed abatholith, or large intrusion of igneous rock.This rock formation never made it to the Earth’s surface untilthe Earth’s crust went through the process of sea floorspreading at the mid-Atlantic Ridge.After a period of time when the seawater and additionalsedimentary rock covered the area, another up thrust of theEarth’s surface occurred. This process, an orogenic uplift(tectonic plate collisions), caused hardened rock from beneathEarth’s crust to elevate, creating a dome-like mountain.Formation of Pikes Peakhttp://www.travellogs.us/2006Logs/Colorado%202006/Pikes%20Peak%2028-06/pp_3418.jpg
Mechanical weathering and erosion caused by glaciers and theirrunoff, or “frost wedging”, has helped to form many features of PikePeak Mountain.Water seeps into the micro fine joints and cracks, causing thealternation of freezing and thawing inside the rocks, splitting themapart.Fluctuation in temperature changes causes expansion andcontraction of the mineral particles found on the mountain, breakingthe minerals apart.Erosion has occurred from dirt trails and roads made to accompanyoff-road vehicle use, hiking, and biking.Alteration of Pikes Peak byErosional Processeshttp://letslearngeology.com/website/wp-content/uploads/2012/11/frost-wedging-rock1.jpg
Animals such assquirrels, porcupines, beavers, skunks, rabbits, coyotes, foxes, elk, black bears and mountain lions play afactor in rock disintegration on Pikes Peak.The penetrating growth of plants and theirroots, such as tundragrasses, mosses, sedges, lichens, grassmeadows, ponderosa pine, pinyon, juniperwoodlands, Goldenrod, Larkspur and Sagebrushsurround the rocks and large boulders, breaking themapart.Biological Weatheringhttp://skywalker.cochise.edu/wellerr/students/pikespeak/project_files/image013.jpghttp://pikespeak.us.com/images/marmot_pp_9400.jpghttp://2.bp.blogspot.com/_GC-ssBUjTkc/TLm2Kl_QwuI/AAAAAAAAAQ8/Ei0K0HGR_NA/s1600/DSCN0269.jpg
About three million years ago, during the Pleistoceneperiod, large glaciers formed during the ice age.These glaciers reshaped the surface of Pikes Peak throughthe process of erosion, transportation, and deposition.Erosion: movement of the ice scraping against the bedrockcaused gouges in the rock of the mountain.Transportation: rock debris that was plucked from thebedrock was frozen to the bottom of the glacier andtransported with the movement of the glacier.Deposition: When the glacier melted, the rock debris wasdeposited into a completely different region, reshaping thelandscape.http://www.geography.learnontheinternet.co.uk/images/glaciation/arete.jpgGlacial Modification of Pikes Peak

Pikes Peak consists entirely of Pink Granite.The color is due to large amounts of potassiumfeldspar found in the granite.Formed from magma that cooled and crystallized atleast 20 miles beneath Earth’s surface.Composition of Pikes Peakhttp://0.tqn.com/d/geology/1/0/p/A/1/pikespeakspar.jpg http://photos-ak.sparkpeople.com/nw/9/8/l981801155.jpg
