Description:
Abstract:
This dataset consists of contours showing generalized lines of equal regolith (unconsolidated sediment) thickness overlying bedrock in the Lost Creek Designated Ground Water Basin, Weld, Adams, and Arapahoe Counties, Colorado. Regolith thickness was contoured manually on the basis of information provided in the dataset ds507_regolith_data. The U.S. Geological Survey prepared this dataset in cooperation with the Colorado Geological Survey and the Lost Creek Ground Water Management District.
Purpose:
This dataset is 1 of 4 datasets (see cross references) developed in support of U.S. Geological Survey Scientific-Investigations Report 2010-5082. This dataset was created to display the generalized apparent thickness of regolith in the Lost Creek Designated Ground Water Basin in vector format.
Supplemental_Information:
The Lost Creek Designated Ground Water Basin is an alluvial valley-fill aquifer in northeastern Colorado that is an important water source for irrigation, municipal, and domestic uses.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Regolith-thickness contours were drawn on the basis of information provided in dataset ds507_regolith_data, which was compiled from Bjorklund and Brown (1957), Nelson, Haley, Patterson, and Quirk, Inc. (1967), HRS Water Consultants, Inc., written commun. (2006), Hurr and others (1972), Skinner (1963), and lithologic logs from wells and test holes on file with the Colorado Division of Water Resources and the U.S. Geological Survey Colorado Water Science Center. In some places, weathered bedrock may have been mapped as regolith because of inaccurate lithologic logs or an indistinct contact between regolith and the underlying bedrock. In particular, lithologic logs of deep wells completed in bedrock were used to map regolith thickness in the southern part of the Lost Creek basin where few other data were available, and regolith thickness determined from these logs might not be accurate because they commonly lacked detailed regolith information.
The accuracy of regolith-thickness contours is variable and depends on the accuracy and number of data used to define the contours at a particular location. Regolith-thickness contours were drawn by using the preponderance of data in a local area and do not necessarily agree with every individual data value. Contours also do not consider local variability in regolith thickness between locations of plotted thickness data. Contours were drawn using an interval of 20 feet and are estimated generally to have an accuracy of about one contour interval, or 20 feet.
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Value: variable
Attribute_Accuracy_Explanation:
Accuracy of regolith-thickness data used for contouring is variable depending on the accuracy of lithologic logs used to estimate regolith thickness. Accuracy of thickness contours is estimated generally to be about one contour interval, or 20 feet.
Logical_Consistency_Report:
Contour lines in this dataset are consistent in their portrayal of regolith-thickness information across the extent of the dataset and were generated by a single individual to ensure data consistency.
Completeness_Report:
Regolith-thickness contours were drawn by hand in the ArcMap editing environment. Hand contouring was used to better interpret the varied and inconsistent data values that sometimes resulted from local irregularities in the bedrock surface, the imprecise bedrock contact, mislocated data points, or conflicting data. Regolith-thickness data were contoured with consideration of apparent data quality, topography, lithology, surface geology, and knowledge of likely depositional and erosional processes leading to the formation of the Lost Creek alluvial valley. In areas where regolith-thickness data were unavailable, the geologic and bedrock contour map by Nelson, Haley, Patterson, and Quirk (1967, plate 2) was used to estimate regolith thickness.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal accuracy of the manually derived contours is variable because of the nature of visually interpreting and interpolating distances between thickness values at data points. In areas where many data were available for contouring, horizontal accuracy is estimated generally as better than about 1,300 feet, or the approximate width of one quarter-quarter section. In areas where few data were available for contouring, horizontal accuracy is estimated generally as better than about 2,600 feet, or the approximate width of a quarter section.
Quantitative_Horizontal_Positional_Accuracy_Assessment:
Horizontal_Positional_Accuracy_Value: 2,600
Horizontal_Positional_Accuracy_Explanation:
Horizontal contour error is estimated on the basis of potential error in data locations and values used to draw contours.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report: Not applicable.
Quantitative_Vertical_Positional_Accuracy_Assessment:
Vertical_Positional_Accuracy_Value: 0
Vertical_Positional_Accuracy_Explanation:
0 used as placeholder for null - vertical accuracy is not applicable for this dataset.

Process_Description:
Dataset ds507_regolith_data was prepared. Data were manually digitized (on-screen) in the ArcMap editing environment based on location information provided by the original data source using, as a backdrop, 1:24,000 digital raster graphic topographic maps.
The following attributes were added to the point dataset: WELL_ID, LOCATION, LAND_ALT, THICKNESS, THICK_QLFR, BR_ALT, BR_QLFR, REMARK, and SOURCE. Regolith-thickness data were compiled from published sources, consultant reports, and lithologic logs of wells and test holes on file with the Colorado Division of Water Resources and the U.S. Geological Survey Colorado Water Science Center.

Process_Description:
Regolith-thickness contours were derived manually from point data in dataset ds507_regolith_data, specifically from the THICKNESS field. Hand contouring was done in the ArcMap editing environment to interpolate contour lines between the data points. Contour lines were drawn using a preponderance of local information from data points and do not necessarily agree with every individual data value. A 20-foot contour interval was used. Where regolith-thickness data were unavailable, the geologic and top-of-bedrock contour map by Nelson, Haley, Patterson, and Quirk (1967, plate 2) was used to estimate regolith thickness and to derive contours.
