Karst And Groundwater What Does This Mean To You Driftless Prairies Two important points were conveyed to the audience: an understanding of what a karst landscape means and how this affects your well and drinking water. the driftless area (southwest wisconsin) is mainly a karst landscape. Because no enormous slabs of ice were present, they did not leave any material behind when they melted, known as glacial drift, hence the term “driftless”. the elevation here ranges from approximately 600 – 1,700ft also means that there are many rare plants and animals that roam in this space.
Karst And Groundwater What Does This Mean To You Driftless Prairies The driftless area (southwest wisconsin) is mainly a karst landscape. what does this mean? karst is a type of landscape formed by the dissolution of its underlying limestone and dolomite (also called carbonate bedrock). The karst workshop offered by the lafayette county conservation and zoning office on march 30, 2017 was a full house with around 65 attendees. two important points were conveyed to the audience: an understanding of what a karst landscape means and how this affects your well and drinking water. Water quickly moves through the cracks in karst and enters the groundwater. these cracks act as direct conduits for pollutants to enter our groundwater, wells, springs, and streams. Driftless wisconsin bedrock consists mostly of karst, a kind of land made up of softer stone, such as limestone, that is riddled with caves and sinkholes. due to this, the driftless wisconsin area hosts a diverse and fragile ecosystem of plants, animals, soils, and open aquifers.

Here in the driftless, it's a never ending cycle: surface water infiltrates into the soils and karst, becoming groundwater that quickly flows from nearby springs to become surface water again. Karst hydrogeology is typified by a network of interconnected fissures, fractures and conduits emplaced in a relatively low permeability rock matrix. most of the groundwater flow and transport occurs through the network of openings, while most of the groundwater storage occurs in the matrix. Disappearing streams can re emerge as large, cold springs. cold streams with cold springs as their sources are superb trout habitat. due to the rapid movement of underground water through regions with karst topography, groundwater contamination is a major concern in the driftless area. “but in crawford county and the rest of the driftless, the karst rocks are not aquifers. they only pass the rainfall water down into aquifers, which are several underground sandstone layers. these include the st. peter, jordan and wonewoc formations.”.
