Information Content
State geologic maps show the general distribution of rocks and sediments exposed at the surface throughout the entire State. Major faults are also shown. Map units are described in terms of lithology and geologic age in an accompanying explanation. The production of most State maps published by the USGS is done in cooperation with the States.

Summary
The United States Geological Survey (USGS) publishes maps in non-quadrangle format. These maps include; a county map series, State base map series, U.S. base maps, a National Park series, and outline maps of the World. Scales range from 1:960 to 1:80 million. Data categories are increasingly generalized as the map scales become smaller. These maps provide data on boundaries, hydrography, Public Land Survey System, transportation, manmade structures, hypsography, vegetative and non-vegetative surface cover (e.g., woods, orchards, lava, sand), geographic reference systems, geographic names, bathymetric contours (in coastal areas). No hypsography data is included in planimetric editions.

Information Content
The State base map series, most at a scale of 1:500,000 and usually published in three separate editions: 1)a base map showing drainage, railroads and populated places; 2) a highway and countour edition with these features superimposed on the base map; and 3) a shaded relief edition with shading superimposed on the highway and contour edition.
As the Nation's principal conservation agency, the Department of the Interior has responsibility for most of our nationally owned public lands and natural resources.
This includes fostering the wisest use of our land and water resources, protecting our fish and wildlife, preserving the environmental and cultural values of our national parks and historical places, and providing for the enjoyment of life through outdoor recreation. The department assesses our energy and mineral resources and works to assure that their development is in the best interests of all our people. The Department also has a mojor responsibility for American Indian reservation communities and for people who live in Island Territories under U.S. administration
A seris of uniform, nationally consistent State Hydrologic Unit Maps that accurately delineate the hydrographic boundaries of major U.S. river basins has been prepared by the U.S. Geological Survey in cooperation with the U.S. Water Resources Council. These maps provide a standardized base for use by Federal and State water resources agencies throughout the country.
The project, initiated in 1972 by the U.S. Geological Survey's Office of Water Data Coordination and supported by the Survey's Resource Planning Analysis Office, has resulted in a standard geographical framework for more detailed water- and related land-resources planning. Prior to publication of these maps, water-resources planners had been using a variety of criteria for naming and coding drainage basins and for delineating hydrologic boundaries. With the publication of the hydrologic unit maps, water-resources managers now have a consistent starting point for planning, as well as an aid for organizing and disseminating data.
These maps, published at a scale of 1:500,000 (1 inch equals nearly 8 miles), present twice the detail of previours riverbasin maps. Using the U.S. Geological Survey State map series as a base, they delineate river basins in the United States that have drainage areas greater than 700 square miles.
The four-color maps show a distinct numberic code assigned to each river basin and provide information on drainage, culture, hydrography, and hydrologic boundaries for each of the 21 regions and 222 subregions designated by the Water Resources Council.
They also depict the boundaries and codes of 352 accounting units within the National Water Data Network and approximately 2,100 cataloging units of the Geological Survey's Catalog of Information on Water Data. The hydrologic units are arranged within each other, starting from smallest (Cataloging Units) to the largest (Regions). Also included on the maps are State and County codes that use the Federal Information Processing Standards (FIPS)
The uses of the State Hydrologic Unit Maps are many, From the standpoint of data collection, storage, and manipulation, a standard coding system is necessary for those wishing to use all data from a particular river basin. The Geological Survey is using the coding system to document all its water-data collection activities and its data-planning efforts. The Survey's NAtional Water Data EXchange (NAWDEX) system has incorporated the code into its computer system to allow all its members easier access to data holdings that consist of more than a billion water-resource measurements. Other Federal agencies (including the Forest Service, Soil Conservation Service, Fish and Wildlife Service, National Park Service, Council on Environmental Quality, National Weather Service, and Water Resources Council) and State, county, and local agencies are using the hydrologic units for codifying and displaying the data that were collected locally and nationwide.
State Hydrologic Unit Maps cost from $1.75 to $5.00.
Sectional Reference Maps from the National Atlas Maps
A series of multicolor planimetric(no contours) maps (also available singly) shows the United States in 21 sections at a scale of 1:2,000,000 (1 inch represents 31.5 miles). Content is similar to that of the U.S. General Reference without shaded relief, but is portrayed in greater detail; national park and forest land, wildlife refuges, and Indian reservations are also shown.
Except for Alaska, California, Montana, and Texas, the sectional Maps have been designed so that each State is shown in its entirety on one sheet>
Each map is printed on one side of a 28- by 19 inch sheet.
