Minnesota Department of Natural Resources Pine county Geologic Atlas, Part B County Geologic Atlas Series C-13 2004 Errata Summary # - Date - Description of Errata - Corrected on the Digital Versions of Printed Plates (Y/N)? CHEMPT.SHP 1 - 03 Oct 2006 - One sampled well in the chempt.shp attribute table has the incorrect aquifer associated with it. Well number 00242042 (Pine City #1) should be listed with an aquifer designation code of "QBAA" instead of "PMHN". The aquifer code QBAA refers to Quaternary aquifer and PMHN refers to Hinckley Sandstone aquifer This error is reflected on two printed plates listed below. N. PLATE 8 - Bedrock Hydrogeology Map 2 - 03 Oct 2006 - One sampled well on the Bedrock Hydrogeology map of plate 08 is symbolized with the wrong symbol. The northernmost sampled well in T29N R21W Section 33 (mixed tritium with estimated carbon-14 age of 1100 years before present) should be symbolized with a hexagon (Quaternary aquifer) and not a circle (Hinckley Sandstone aquifer). N. PLATE 8 - Figure 2c 3 - 03 Oct 2006 - The same well (item #2 above) should be displayed on Figure 2c of plate 08 as a hexagon indicating a Quaternary aquifer with mixed tritium and estimated carbon-14 age of 1100 years before present. N. PLATE 10 - Pollution to Sensitivity of the Uppermost Bedrock Aquifers Map 4 - 03 Oct 2006 - The same well (item #2 above) is symbolized incorrectly on the Sensitivity to Pollution of the Uppermost Bedrock Aquifers map on Plate 10. The northernmost sampled well in T29N R21W Section 33 (mixed tritium with estimated carbon-14 age of 1100 years before present) should be symbolized with a hexagon (Quaternary aquifer) and not a circle (Hinckley Sandstone aquifer).
