Today an increasing number are backcountry snowboarders and gasoline crazed snowmobilers (whyfiles.org). An Avalanche is defined as a "rapidly descending large mass of snow, ice, soil, rock or mixtures of these materials, sliding or falling in response to the force of gravity." All that is necessary for an avalanche is a mass of snow and a slope for it to slide down. Avalanches occur regularly on mountains around the world, and are harmless, unless someone happens to be in the way. They tend to run down the same pathways every year, and danger zones are usually well-known (infoplease.com).
September 9, 1999, day two, involved three main areas of study: the Bridgenorth esker (Map 3), Mark S. Burnham Park (Map 4), and the Rice Lake drumlin (Map 6). These sites are in areas of thick glacial deposits. September 10, 1999, day three, involved studying the Warsaw Caves (see Map 5) as a transition zone between Precambrian Shield rock to the north and Paleozoic rock to the south. A general map of the entire study region is provided by Map 1. Section 1: Geology Part I: Bedrock Knob The site visited on this day was informally known as the Bedrock Knob (NTS grid reference: 120 342).
Following frequent changes in climate in the Quaternary period, glaciers have advanced and retreated leaving a layer of glacial deposits in their wake (Natural England). These deposits were transported downstream via meltwater rivers to lowland areas, making them fertile and very useful for pastoral farming. As such, lowland areas have become popula... ... middle of paper ... ...ved January 16, 2011, from Crimestop Guards: http://www.crimestopguards.co.uk/manchester.htm Geology Roam. (n.d.).

This river left behind deposits that after millions of years transformed into the parks sandstone bedrock. As the ice age came into effect, this river froze and became part of a glacier that had an even bigger effect on the landscape of the valley. These glaciers scraped through northeastern Ohio and in the process left behind deposits that now make up the parks fertile soil (“Rock, Ice, and River”). The American Indians that first called this area of northeastern Ohio have had an immense impact on it. Even the name of the river and consequentially the valley is a native word meaning "crooked river"(“Industrialization”).

The Grand Canyon became a national park in 1919. It was the seventeenth national park in the United States and one of our planet’s most spectacular landscapes. American Indians have been living in or around the canyon for thousands of years. The rock layers that make up the canyon walls change colors from tan to gold and from brown to black. The Grand Canyon is a remarkable feature in Arizona, but why is it so different from most other canyons and valleys and how did it originate?
Paleontologists have discovered a huge, 100 km, slab of rock that spans the last 40 million years of the Mesozoic era. Exploration of this site through tunneling is believed to present a more extensive record of polar dinosaurs as they were over the Jurassic and Cretaceous periods. (1) Works Cited 1) Rich, T.H., P.
