<br />
<br />The U.S. Geological Survey (USGS) has
<br />served as the Nation's principal collector,
<br />repository, and interpreter of earth science
<br />data for more than a century. In this capacity,
<br />the USGS in Colorado works in partnership
<br />with more than 90 local, State, and Federal
<br />agencies. Cooperative activities include
<br />water-resources data collection, interpretive
<br />water-availability and water-quality studies,
<br />mineral-resource assessments, and mapping.
<br />In activities with local and State agencies,
<br />USGS and non-Federal funds are typically
<br />matched equally. The USGS also is involved
<br />with several community outreach activities,
<br />which include educational presentations at
<br />schools and information booths at community
<br />events. The USGS also supports the Colorado
<br />Water Resource Research Institute, which
<br />conducts research, education, and informa-
<br />tion and technology-transfer programs. This
<br />Fact Sheet describes some of the current
<br />USGS activities in Colorado.
<br />
<br />Geologic Mapping Along 1-70
<br />
<br />Rapid growth along the 1-70 corridor in
<br />the western part of the State between the Utah
<br />border and the Frisco-Dillon area has
<br />prompted the USGS and the Colorado Geo-
<br />logical Survey to form cooperative geologic
<br />mapping teams. At least 36 detailed geologic
<br />maps of the corridor are planned over about a
<br />5-year period. Many geologic hazards, such
<br />as landslides, debris flows, and sinkholes, can
<br />be avoided if the information on detailed geo-
<br />logic maps is used to make land-use deci-
<br />sions. People in Mesa, Garfield, Eagle, and
<br />Summit Counties and city, State, and Federal
<br />agencies can use these maps to make deci-
<br />sions intended to mitigate or avoid geologic
<br />hazards, and, therefore, potentially save lives,
<br />money, and property.
<br />
<br />Landslide Hazards
<br />
<br />Huge, ancient landslides cover mountain
<br />sides throughout western Colorado; many of
<br />these slides are near towns, recreational facil-
<br />ities, railroads, and major highways. If any of
<br />these landslides were reactivated by human
<br />activities, earthquakes, or climate change,
<br />then nearby towns or facilities could be
<br />destroyed. USGS scientists in Lake City and
<br />
<br />Grand Mesa are studying large, ancient and
<br />modern landslides. Through these studies, the
<br />USGS can document many of the conditions
<br />that caused the landslides and formulate
<br />models to predict where and when landslides
<br />can occur or be reactivated by changing
<br />climate or earthquakes.
<br />
<br />Oil-Resource Assessments
<br />
<br />Working with the U.S. Forest Service
<br />(USFS) and the State of Colorado, the USGS
<br />assessed the petroleum-resource potential of
<br />the White River National Forest. This assess-
<br />ment provided these agencies information to
<br />formulate development plans that consider
<br />natural ecosystem preservation.
<br />
<br />The USGS, in cooperation with the U.S.
<br />Department of Energy (DOE), recently com-
<br />pleted an assessment of the petroleum poten-
<br />tial of two Naval Oil Shale Reserves in
<br />Colorado.
<br />
<br />National Water-Quality
<br />Assessment Program
<br />
<br />The long-term goals of the National Water-
<br />Quality Assessment (NAWQA) Program are
<br />to describe the status and trends in the quality
<br />of a large, representative part of the Nation's
<br />surface- and ground-water resources and to
<br />identify the natural and human factors that
<br />affect their quality. The NAWQA Program
<br />produces water-quality information that is
<br />useful to policymakers and water managers at
<br />the local, State, and national levels.
<br />
<br />NA WQA Program studies of three river
<br />basins in Colorado-the South Platte, the
<br />_!:!"I:lRer Colorado, and the Rio Grande-are
<br />underway; another, the upper Arkansas, is
<br />planned (fig. I). Communication pnd coordi-
<br />nation among the USGS and the water-
<br />management and other water-resource agen-
<br />cies are essential to the NAWQA studies in
<br />the State. As results become available, the
<br />findings are distributed in technical and
<br />public information reports to local, State, and
<br />Federal agencies.

<br />largest coal-bed methane field in production
<br />in the world. Total coal-bed methane
<br />resources for the Basin have been estimated to
<br />be 50 trillion cubic feet of gas, and as much as
<br />one-half of that amount is considered to be
<br />recoverable. For the first time, the amount of
<br />gas produced in 1994 from coal beds of the
<br />Fruitland Formation surpassed the production
<br />of gas from the Basin's conventional sand-
<br />stone reservoirs. The rapid development of the
<br />coal-gas resources was made possible by
<br />detailed studies of the Fruitland coal beds
<br />published by the USGS and the Colorado
<br />Geological Survey in the 1970's.
