The Decorah Edge

According to the Olmsted County website, Decorah Edge is: "defined as the area in which the Decorah, Platteville, or Glenwood formation is the first encountered bedrock according to the 'Bedrock Geology: Steele, Dodge, Olmsted and Winona Counties' data plate produced by the Minnesota Geological Survey – University of Minnesota in 2004, as modified by field investigation or more precise mapping; and having a depth to bedrock of less than twenty-five feet according to the 'Depth to Bedrock: Steele, Dodge, Olmsted and Winona Counties' data plate produced by the Minnesota Geological Survey – University of Minnesota in 2004, as modified by field investigation, reliable well logs, or more precise mapping; and for which there are contiguous adjacent areas with the Cummingsville or higher formations as the first encountered bedrock."

Soil Erosion

Soil erosion happens when disturbances to the ground: traffic & weather.
 

Water Shed

According to the Minnesota Environmental Partnership website, without a proper soil layer, the water shed is affected by increasing amounts of nitrates and other contaminants, changes the pH of the soil affecting native species.
 

Changing Weather Climate

According to a Scientific American article, "With climate models predicting the region will increasingly swing between droughts and heavy downpours, researchers say the situation threatens to deteriorate." Nitrates in exessive amounts are known to be particularily harmful to infants.
