The Geological Survey, Department of Environment and Natural Resources, engages in an ongoing data collection andinterpretation process. An outcome of that process is to reflect those interpretations on maps such as this one. Reasonableefforts have been made to ensure that this map accurately reflects the source data used in its preparation. This map is datespecific. As additional data become available, geologic interpretations may be revised and the map may be updated by theGeological Survey. This map should not be enlarged or otherwise used in an attempt to interpret more detail than can beseen at the 1:100,000 scale.

This map is intended for use as a tool to aid in identifying areas underlain by aquifer material. The aquifer materials shown on this map are categorized below. This map does not show individual aquifers. There may be more than one type of aquifer material present in an area. However, only the aquifer material that would be first encountered is shown. Within the boundaries of any given map unit, there may be localized areas where aquifer material is absent. The thickness and permeability of aquifer material may vary significantly. Also, no attempt wasmade to distinguish between saturated and unsaturated material. Therefore, not all of the areas defined on this map may be an aquifer. Site-specific information should always be examinedwhen making land management or water development decisions.

Explanation

Alluvium: Consists of clay and silt with minor amounts of sand and gravel that, in general, directly overlie a major aquifer

Outwash: Sand and gravel with minor amounts of clay; first occurrence is generally at land surface

Sand and Gravel: May not be uniform in depth and thickness and may be discontinuous in lateral extent

Niobrara Formation: Consists of calcareous marl and chalky limestone, typically fractured

Sand and Gravel: May not be uniform in depth and thickness and may be discontinuous in lateral extent

Niobrara Formation: Consists of calcareous marl and chalky limestone, typically fractured

Sand and Gravel: May not be uniform in depth and thickness and may be discontinuous in lateral extent

Niobrara Formation: Consists of calcareous marl and chalky limestone, typically fractured

Alluvium: Consists of clay and silt with minor amounts of sand and gravel that, in general, do not directly overlie a major aquifer

Cretaceous Undifferentiated: Chalk or quartzose sandstone, interbedded with clay or black shale; may include "quartzite wash"Dakota Formation: Consists of interbedded sandstone, siltstone, and shale

Sioux Quartzite: Consists of orthoquartzite with minor conglomerate, sandstone, and mudstone. The quartzite is typically pinkish in color and very hard. It is not generally an aquifer material; however, locally it yields water from fractures and porous zones
