  • NATURAL RESOURCES (Updated Excerpt from Jo Daviess Comprehensive Plan Baseline Data)
    ATTACHMENT F: NATURAL RESOURCES (Updated excerpt from Jo Daviess Comprehensive Plan Baseline Data) The natural resources in Jo Daviess County are unique relative to the rest of the state and much of the mid-west because the county is part of the Wisconsin Driftless Region bypassed by continental glaciers of the Ice Age. This region covers parts of southern Minnesota and Wisconsin, Northwestern Illinois and Northeastern Iowa. Glaciated areas were leveled, strewn with glacial debris or "drift" and dotted with lakes and ponds. The driftless areas, on the other hand, have bedrock close to the surface into which deep valleys have been carved by millions of years of weather and erosion. In Jo Daviess County, streams are numerous and the only two lakes are man-made. The relief from the higher ridges to the valley floors is typically 300 feet or more creating a rugged and scenic landscape. Ecosystems can be found in this landscape that are older than those found in glaciated areas. Geology The topography of Jo Daviess County is characterized by rugged relief unique to most of Illinois. Our county, located in the far northwestern corner of the state, is in an area spared by the major glaciations of the last two million years. It is, accordingly, called the "Driftless Area" by geologists, the term "drift" referring to material deposited by glacial activity. The visible landscape that we see today began during the Paleozoic Era (570 to 245 million years ago) when shallow seas repeatedly inundated the interior of the continent. Shells of marine animals, along with muds, silts and sands from eroding highlands, were periodically deposited in those sea bottoms.

  • Leif Segen University of Northern Iowa Summer 2015 Site Identification
    Geology of Wellington Heights Leif Segen University of Northern Iowa Summer 2015 Site Identification The site under consideration is the Wellington Heights neighborhood in the Southeast quadrant of Cedar Rapids, Linn County, Iowa. 7.5’ by 7.5’ USGS Topographic Quadrangle The neighborhood can be found on the Cedar Rapids South, IA map, digitally published by the United States Geological Survey on April 25, 2013. Its topological data is based on the 1999 National Elevation Dataset. Public Land Survey System According to the original Public Land Survey of the area, the neighborhood is located at “PM05, T83N, R7W, Sec.22,” or centrally located in Figure 1 Excerpt from USGS 7.5' x 7.5' Quadrangle for Cedar Rapids South, IA, Iowa-Linn Co. Section 22 of Township 83 North, Range 7 West, fifth Principal Meridian. This means that the location is approximately 7 x 6 miles = 42 miles west and 83 x 6 miles = 498 miles north of what is now Louisiana Purchase Historic State Park. This is the intersection of a north-south meridian starting at the old mouth of the Arkansas River and the east-west baseline starting at the old mouth of the St. Francis River (34° 38’ 44.0” N, 91° 3’ 42.0” W). This location, as with the rest of Iowa, Arkansas, Minnesota, North Dakota, and the eastern portion of South Dakota, is part of the first Public Land Survey done after the Louisiana Purchase. Latitude and Longitude The neighborhood’s centroid has approximate latitude of 41.9851782N (or 41° 59’ 6.6”N) and longitude of 91.6503899W (or 91°39’1.4”W).

  • Driftless Area - Wikipedia Visited 02/19/2020
    2/19/2020 Driftless Area - Wikipedia Visited 02/19/2020 Driftless Area The Driftless Area is a region in southwestern Wisconsin, southeastern Minnesota, northeastern Iowa, and the extreme northwestern corner of Illinois, of the American Midwest. The region escaped the flattening effects of glaciation during the last ice age and is consequently characterized by steep, forested ridges, deeply carved river valleys, and karst geology characterized by spring-fed waterfalls and cold-water trout streams. Ecologically, the Driftless Area's flora and fauna are more closely related to those of the Great Lakes region and New England than those of the broader Midwest and central Plains regions. Colloquially, the term includes the incised Paleozoic Plateau of southeastern Minnesota and northeastern Relief map showing primarily the [1] Iowa.

Kolata and T. C. Buschbach ABSTRACT The Plum River Fault Zone extends westward from Leaf River, Illinois, across Ogle and Carroll Counties to an area south of Maquoketa, Jackson County, Iowa. Field observations, well records, cores, and refraction seismic data from Illinois indicate that the fault zone is generally- less than half a mile wide, with strata downthrown 100 to 400 feet on the north. The faulting occurred after Niagaran (middle Silurian) time and before mid-Illinoian (Pleistocene) time. Four minor structural features adjacent to the Plum River Fault Zone are herein named; they are the Forreston Dome, the Brookville Dome, the Leaf River Anticline , and the Uptons Cave Syncline. INTRODUCTION Geologic studies of proposed sites for nuclear power-plants and under- ground gas storage projects in northwestern Illinois have furnished new information about the structural geology of the area and have shown the need for detailed understanding of the structural setting. This investigation was undertaken to determine the nature and extent of known faulting near Savanna, Carroll County, Illinois.
