Purpose | This table summarizes the textural characteristics for the samples taken within the county. Six sieves were used to determine the textural characteristics of the deposit. This table is a very gross indication of the textural characteristics and should only be used as a large-scale guide.

Data Quality |
Attribute Accuracy | These numbers represent a single drill hole within a deposit. However, the deposit may vary in textural composition very much from one end to the other, or the top 10 feet may be very different from the lower 10 feet. Thus, great care must be taken when interpreting this information.
Logical Consistency | NA
Completeness | All available data were summarized and are incorporated within this table.
Horizontal Positional Accuracy | NA
Vertical Positional Accuracy | NA
Lineage | The ranges of values were taken directly from sieve data tested at the MN-DNR Hibbing laboratory. A deposit may vary in textural composition very much from one end to the other, or the top 10 feet may be very different from the lower 10 feet. Thus, great care must be taken when interpreting this information.

Entity-Attribute Overview | The ranges of values were derived from sieving samples from a deposit(s). However, a deposit may vary in textural composition very much from one end to the other, or the top 10 feet may be very different from the lower 10 feet. Thus, great care must be taken when interpreting this information. These data can be related to their locations, stored in the fieldobs.shp, by relating on the ident field.
