Purpose: To illustrate quadrangle boundaries and names in Colorado. Supplemental_Information: Parts of these datasets were borrowed from previous USGS datasets, other parts were created for this data release.

The U.S. Geological Survey (USGS) makes no warranties related to the accuracy of the data and users are required to determine suitability of use for any particular purpose. This digital map is not to be construed as a legal representation of the quadrangle boundaries. All of the grids were constructed for this release using standard 7.5 minute, 30 minute, 1 degree, and 2 degree digital grids. Any hardcopies utilizing this data set shall clearly indicate this source. If the user has modified the data in any way, (s)he is obligated to describe the types of modifications performed on the hardcopy map. User specifically agrees not to misrepresent this data set, nor imply that changes were approved by the USGS.

These names were cross checked against the Colorado Index to topographic and other Map Coverage released periodically by the USGS and several errors were corrected. All quadrangle names for the 1:100,000 and 1:250,000 quadrangles were entered by hand according to the USGS's Colorado Index to topographic and other Map Coverage. Quadrangles that include Colorado and overlap nearby states (Utah, Wyoming, Nebraska, Kansas, Oklahoma, New Mexico, and Arizona) are included. Completeness_Report: The data are considered complete for the purpose of displaying quadrangles in Colorado. Logical_Consistency_Report: The files were created in MapInfo Pro 6.5 using the grid utility.

The remaining fields were used to query the data and to derive the USGS Quad_ID. CO_100K: Only the first two fields, Description (the USGS quadrangle name) and ID_# (the USGS quadrangle identification number) are relevant. (Col_Name and Row_Name are indexes used to query the data to create the ID_# field.) CO_250K: Quad250K (the USGS 1:250,000-scale quadrangle name followed by the state(s) if not mostly Colorado), Quad_Id (the USGS quadrangle identification number).
