Manchester State Park, Kitsap Peninsula, Washington: West Beach Outcrop Geology Jason Ott The west beach at Manchester State Park consists of roughly 200m of exposed outcrops with well bedded strata of consisting of the Blakeley formation, of Oligocene age, and poorly consolidated beds of Quaternary age. The northern boundary of the area of interest begins at the southern edge of Middle Point and area terminates at Clam Bay to the south. The Blakeley formation consists of alternating sequence of coarse sandstones, mudstones, and sub-rounded/brecciated conglomerates. The formation strikes 269°, and dips 41°N. The sandstone and mudstone members are typically 30-50cm thick.
Mesa Verde is most well known for its cliff dwellings found in the sandstone of its dynamic landscape. The Mesa Verde National park was originally established for the main purpose of preserving these very same archaeological sites. Without the geology of the area these dwellings might never have come to be, or preserved so splendidly. While it has many different geological formations on the property John Carrara states that “The Mesa Verde is essentially a broad, flat, upland surface sloping gently to the south and dissected by deep canyons containing ephemeral streams.” (Carrara 2014) The majority of the rock formation found in the park were formed from sediments from the crustaceous age (Carrara 2014) . The four most prevalent forms are
This granite monolith extends about 3,000 feet from base to top and is one of the world's favourite challenges for rock climbers and BASE jumpers. El Capitan is exclusively composed of granite. A pale,coarse-grained granite emplaced approximately 100 million years ago.

This mountain range is actually an offshoot of the Sierra Nevada.
• Introduction: Organ pipe park is part of the Greater Western Volcanic Plains , which is the third largest lava formation in the word . The span of these planes runs from Melbourne to Mt Gambier which is situated in South Australia . A million years ago , at Mount Holden were keilor Plains are located , The continual flowing lava of lava in molten form over the plains , filled the preexisting valleys and depressions on the land surface , later on cooled and reached a solid state to form basalt , The formations of columns is further explained in the weathering and structural features below • Weathering: The rock formation showcases the growth of valley incision caused by the down cutting action of the water stream from Jacksons Creek. Another Cause of weathering can be the growth of plant life on the rock surface which increases humidity between rock imperfections, this can cause chemical and physical breakdown of the surface micro layer of the rock . The saplings budding in a fracture and growing plant roots will apply physical pressure and will provide a passageway for chemical and water permeation.
First of all, Rock of Cashel exactly stands for circular stone fort. The Rock of Cashel revealed many burials as the Rock of Cashel formed, but something happened, we will get into that a little bit later. The Rock of Cashel has many different stories of how the Rock of Cashel was formed. The Rock of Cashel is made of dry stone. The Rock of Cashel is different heights the circular one is the tallest.
Enlarged westward for nearly 200 miles to the Manti-la-sal Mountains of central Utah. Immediately the town of southwest, tributaries of the Colorado river carved through the edge of the high Uncompahgre Plateau that borders the Colorado for some distance, and the most scenic area, about 10 by 5 miles, is contained within the national monument. This accommodates the four main canyons, trimming into the upland for several miles, with some small ravines, remote towers and pinnacles and numerous sandstone
ornata inhabits the central and southwestern United States and northwestern Mexico from the Rocky Mountains in the west to the Mississippi River in the east. Generally speaking, the northernmost reaches of its range include South Dakota and Wisconsin, and the southernmost boundary of its range occurs in northwestern Mexico (Terrapene ornata, n.d.). Found at elevations from sea level to approximately 21,000 feet (6,500 meters), with the average being approximately 5,000 feet (1,500 meters) of elevation, the species prefers a year-round temperature span of 77 to 86° F (25 to 30° C) (Terrapene ornata, n.d.). While the two subspecies share an overlapping range in the Great Plains of the United States, T. o. ornata occurs primarily in the central United States in the states of Kansas, Nebraska, Oklahoma and Texas. On the other hand, T. o. luteola occupies Arizona, New Mexico and western Texas up to the fringes of the desert in the southwestern United States as well as the states of Chihuahua and Sonora in northwestern Mexico (Terrapene ornata,
Utah has a state fossil, it is the Allosaurus. Now let’s get to some important facts about Utah. Utah is the 45th state to be discovered. Before then people have traveled there so I’ll tell you some about them people. In 1776, the Dominguez-Escalante expedition explores the region.
The clays and poorly consolidated rock make the badlands easily eroded (Graham, 2008). The Badlands National Park was formed from the deposition of these poorly consolidated rocks. After the rocks were deposited they experience a lot of erosion, and the erosion is what shaped the badlands into what we see today. In The Badlands National park you can see the Pierre Shale, the Chadron Formation, and the Brule Formation (). Within the Brule Formation there is a red paleosol layer ().
There are two types of techniques that are used to date the rocks and uncover the history. First is relative dating, which can determine the order or sequences of events as they happened and second, is absolute age which determinations are numeric and identify the specific years when different things happened. www.nature.nps.gov/geology/parks/grca/age/index.cfm Allyson Mathis and Carl Bowman, 2006 “The Grand Canyon Age of Rocks: The Numeric Age of Rocks Exposed Within Grand Canyon, National Parks Service, U.S. Department of The
Along the North and South Carolina border is the Whitewater Falls Chain-six different waterfalls that are just one attraction in a unique part of the Blue Ridge Mountains. One writer of this wilderness area described it as a blue wall. For about 70 miles there is what 's called an escarpment. This is shear rock face lining deep gorges. The gorges are deep ravines that were created by the rushing waters.
