Analysis of surficial deposits provides much of the evidence for changes in landforms over time. These deposits may be residual materials, formed in place by weathering system of the digestive system underlying formations, or may have been formed elsewhere and then transported by wind, water, or humans to their present site of deposition.

They include system of the digestive system sediments and soils, which are commonly confused in the field although each originates by different processes and each yields different kinds of information. Both geomorphology and surficial deposits are the principal subjects of tension headache other publications and will not be covered in great detail here.

This book aims to cover in more detail fields that are universally acknowledged to be important for archaeology but are generally ignored in the "geoarchaeology" literature. Those seeking more information on geomorphology and surficial deposits should refer to other publications. The kind and amount of surficial materials change with the changing land surface and climatic conditions and so offer the best evidence regarding the evolution of the landscape.

An understanding of these changes on a site will allow a re-creation of the paleoenvironment at the time of occupation and a modeling of the prehistoric land-use patterns.

Archaeological exploration in an area is facilitated by first pinpointing desirable habitation sites of the time and then targeting these sites for geophysical prospecting. After a site has been discovered, geophysical and geomorphic-sedimentologic information can help develop excavation strategies.

Such information commonly allows a better idea of the distribution and nature of buried artifacts and may explain anomalous surficial redistribution of artifacts, for example, by downslope wash or sediment burial. The first study in a new area proposed for any detailed archaeological work should be geomorphic-surficial geology.

It can be carried out in three distinct phases:1. Geomorphic mapping affords meaningful descriptions of the landforms, drainage patterns, surficial deposits, tectonic features, and any active geomorphological processes.

In the Pacific Northwest, volcanoes, tectonic movement, glaciers, rain, snow, wind, vegetation, animals, and people all shape the landscape at different scales of time and space.

Of particular interest in the region is the form and processes of rivers, a branch of the science termed fluvial geomorphology. Rivers are extremely important to the people, plants, and animals in the Pacific Northwest, providing water for ecosystems and transporting sometimes large amounts of sediment downstream.

To understand how rivers move and change over time, the USGS is studying river hydraulics, sediment transport in rivers from the mountains to the ocean, the role of large wood in influencing river shape, impacts on the aquatic ecology and fish in rivers, and how river flooding worsens or improves over time.

The Issue: A large, clay-rich active landslide on the western flank of Sumas Mountain in Whatcom County, Washington, is a significant source of sediment to Swift Creek and the salmon-bearing Sumas River. The landslide contains naturally occurring serpentinite that weathers to chrysotile asbestos and elevated levels of metals.

The Issue: The Elwha River Restoration Project is the largest single restoration action planned for the Puget Sound region in the foreseeable future and is a high priority for the Puget Sound Partnership.

It agree, it is the amusing information

It is a pity, that now I can not express - I hurry up on job. But I will be released - I will necessarily write that I think.
