Soil Survey of Allen County, Ohio United States In cooperation with Department of Ohio Department of Agriculture Natural Resources, Soil Survey of Division of Soil and Water Natural Conservation; Ohio Allen County, Ohio Resources Agricultural Research and Conservation Development Center; Service Ohio State University Extension; Allen Soil and Water Conservation District; and Allen County Commissioners i How To Use This Soil Survey General Soil Map The general soil map, which is a color map, shows the survey area divided into groups of associated soils called general soil map units. This map is useful in planning the use and management of large areas. To find information about your area of interest, locate that area on the map, identify the name of the map unit in the area on the color-coded map legend, then refer to the section General Soil Map Units for a general description of the soils in your area. Detailed Soil Maps The detailed soil maps can be useful in planning the use and management of small areas. To find information about your area of interest, locate that area on the Index to Map Sheets. Note the number of the map sheet and turn to that sheet. Locate your area of interest on the map sheet. Note the map unit symbols that are in that area. Tur n to the Contents, which lists the map units by symbol and name and shows the page where each map unit is described. The Contents shows which table has data on a specific land use for each detailed soil map unit. Also see the Contents for sections of this publication that may address your specific needs. ii This soil survey is a publication of the National Cooperative Soil Survey, a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (formerly the Soil Conservation Service) has leadership for the Federal part of the National Cooperative Soil Survey. Major fieldwork for this soil survey was completed in 1997. Soil names and descriptions were approved in 1997. Unless otherwise indicated, statements in this publication refer to conditions in the survey area in 1997. This survey was made cooperatively by the Natural Resources Conservation Service; the Ohio Department of Natural Resources, Division of Soil and Water Conservation; the Ohio Agricultural Research and Development Center; the Ohio State University Extension; and the Allen County Commissioners. It is part of the technical assistance provided to the Allen Soil and Water Conservation District. Soil maps in this survey may be copied without permission. Enlargement of these maps, however, could cause misunderstanding of the detail of mapping. If enlarged, maps do not show the small areas of contrasting soils that could have been shown at a larger scale. A State Geographic Database (SSURGO) is available for the county. This database consists of a soil map at a scale of 1:250,000 and descriptions of groups of associated soils. It replaces the general soil map published in older soil surveys. The map and the database can be used for multi-county planning, and map output can be tailored for a specific use. More information about SSURGO for this county, or any portion of Ohio, is available at the local office of the Natural Resources Conservation Service.

An Abstract of The Deglacial Chronology of the Sturgis Moraine in South-Central Michigan and Northeast Indiana by Jennifer M. Horton Submitted to the Graduate Faculty as partial fulfillment of the requirements for the The Master of Science Degree in Geology The University of Toledo August, 2015 Understanding the timing and rate of ice retreat in the Great Lakes Region is critical to understanding any relationship between ice lobes and climate during the Late Wisconsinan time period. The purpose of this study is to constrain the age of the Sturgis Moraine, an end moraine of the Saginaw Lobe in south-central Michigan using minimum-limiting radiocarbon and OSL ages. Previous correlations between till stratigraphy and end moraines suggest that the Sturgis Moraine formed between 15,500 and 16,100 14C yrs BP, but with little direct supporting chronologic data. To date the Sturgis Moraine, Livingstone sediment cores were collected from three scour lakes within tunnel channels at the distal side of the moraine.

An Abstract of The Chronology of Glacial Landforms Near Mongo, Indiana – Evidence for the Early Retreat of the Saginaw Lobe by Thomas R. Valachovics Submitted to the Graduate Faculty as partial fulfillment of the requirements for the Master of Science Degree in Geology The University of Toledo August 2019 The Saginaw Lobe of the Laurentide Ice Sheet occupied central Michigan and northern Indiana during the last glacial maximum. Evidence exists that the Saginaw Lobe retreated earlier than its neighboring lobes but attempts to constrain this retreat using radiocarbon dating methods has led to conflicting results. Optically stimulated luminescence dating (OSL) offers an alternative methodology to date deglacial deposits. The Pigeon River Meltwater Channel (PRMC) was formed by a large, erosional pulse of meltwater that exited the ice sheet and eroded through the deglaciated landscape previously occupied by the Saginaw Lobe. Sediments that partially fill the PRMC were dated using OSL. Minimum ages for the retreat of the Saginaw Lobe were acquired to test the hypothesis that the Mongo area is ice free by 23 ka.

    Buried Pinchout of Saginaw Lobe Drift in Northeastern Indiana 1 N. K. Bleuer and M. C. Moore Indiana Geological Survey, Bloomington, Indiana 47401 Abstract Subsurface data for Allen County, Indiana, indicate that the till of the Saginaw Lobe (unnamed member of the Lagro Formation) is a discrete unit separable from the superjacent clayey till of the New Holland Till Member of the Lagro Formation, and from hard loamy till units below that are presumed to include the Trafalgar Formation. The till of the Saginaw Lobe has sandy loam to loam texture, stiff consistency, and contains fragments of coal, tillite, and jasper conglomerate. Although the unit is map- pable, a consistent means of petrographically differentiating this till from underlying hard tills of similar texture has not yet been found. The extent of Saginaw till beneath till of the Erie Lobe can be mapped. This onlap- underlap condition in northeastern Indiana has been recognized since the late 1800's, but its great extent has been documented only recently. The Saginaw Lobe till extends southeastward from its areas of outcrop to northwestern Allen County, where its buried feather edge roughly parallels the Eel River sluiceway. The unit is exposed at several places in Cedar Creek canyon. Although the Saginaw drift (and ice?) was subsequently covered by ice and drift of the Erie Lobe, Saginaw-drift topography was not obliterated, and it influenced the piracy of Cedar Creek from the Eel to the St. Joseph drainage. The topography of buried Saginaw drift may have been the dominant influence on the surface relief and local morainal topography in northwestern Allen County and perhaps elsewhere in north- eastern Indiana.

  • Evidence of Sequence and Age of Ancestral Lake Erie Lake-Levels, Northwest Ohio
    62 ANCESTRAL LAKE ERIE LEVELS VOL. 115 Evidence of Sequence and Age of Ancestral Lake Erie Lake-Levels, Northwest Ohio TIMOTHY G. FISHER, Department of Environmental Sciences, University of Toledo, OH, USA; JOSEPH D. BLOCKLAND, Department of Environmental Sciences, University of Toledo, OH, USA, North Dakota Geological Survey, Bismarck, ND, USA; BRAD ANDERSON, Department of Environmental Sciences, University of Toledo, OH, USA, Nyrstar Tennessee Mines, Gordonsville, TN, USA; DAVID E. KRANTZ, Department of Environmental Sciences, University of Toledo, OH, USA; DONALD J. STIERMAN, Department of Environmental Sciences, University of Toledo, OH, USA; RONALD GOBLE, Department of Earth and Atmospheric Sciences, University of Nebraska at Lincoln, Lincoln, NE, USA ABSTRACT. While the general scheme of the retreat of the Late Wisconsinan glacier from the ancestral Lake Erie basin is understood, the sequence and timing of those movements that caused lake-level changes are not well documented. Ground penetrating radar (GPR), electrical resistivity (ER), and optically stimulated luminescence (OSL) techniques were used to analyze beach and sand dune formations in the Wauseon area in northwest Ohio. The beaches showed no evidence of being flooded after deposition. Thirteen (13) new OSL ages revealed a short time of approximately 1000 years (16.9–15.9 ka) for formation of the Maumee, Arkona and Whittlesey shorelines. Evidence supporting the Ypsilanti lowstand in the ancestral Lake Erie basin was not observed within two sequences of glacial lacustrine sediments. The results of OSL dating of sand dunes indicate a period of older activity (~14–15 ka) and confirmation of previous work that documented activity during the Younger Dryas cold period (~13–11.5 ka).

    Glacial Stratigraphy of the Fort Wayne Area and the Draining of Glacial Lake Maumee 1 N. K. Bleuer and M. C. Moore Indiana Geological Survey, Blooming-ton, Indiana 47401 Abstract Two major glacial till sequences are present in the Fort Wayne area. The upper sequence consists of the clayey tills of the Lagro Formation and the lower consists of extremely hard loam tills that are correlated with the Trafalgar Formation. Both are Wisconsinan in age. The morphology and development of the Fort Wayne Outlet, the Six Mile Creek channel, and the Wabash-Erie Channel were controlled by a combination of bedrock topog- raphy, early glacial discharge routes, the lithology and thickness of glacial materials, and the most recent ice-controlled drainage. The morphology of the lake floor and the morphology and postglacial stratigraphy of the outlets of glacial Lake Maumee suggest that all three of the classic lake levels could have discharged at Fort Wayne and that the classical 800-foot, 760-foot, and 780-foot sequential order is without foundation. The lower hard tills could have slowed temporarily the downcutting of the Fort Wayne Outlet and stabilized the intermediate lake level. Introduction An ongoing study of the environmental geology of the Fort Wayne area, Allen County, Indiana, has required that we develop much more detailed knowledge of the glacial stratigraphy than has been known here- tofore. Therefore, we have accumulated a considerable amount of data in the form of water well records, engineering boring logs, shallow refrac- tion seismic records, measured sections of natural and artifical exposures, and logs of our own power augering.

The watershed drainage area is just over 380,265 acres. The watershed covers four Indiana counties. It is subdivided into 38 subbasins represented on the map by 12 digit HUCs (Figure 2-1). One of two St. Joseph Rivers in Indiana, this river originates in Michigan and flows through Ohio before turning into northeastern Indiana. At the point where the St. Joseph converges with the St. Mary's River to form the Maumee River, the French and then the British built forts which eventually came to be called Fort Wayne after General Anthony Wayne. During the nineteenth century the St. Joseph River was a center of attraction as steamboats plied its waters and part of the river was diverted to supply water for the central section of the Wabash-Erie Canal (IDNR 1999).

  • The Original Vegetation of Van Wert County, Ohio
    THE ORIGINAL VEGETATION OF VAN WERT COUNTY, OHIO E. E. GOOD Department of Zoology and Entomology, The Ohio State University, Columbus 10 INTRODUCTION Ohio is an area where profound changes have taken place since the coming of the first settlers. This is true for all of Ohio but perhaps most strikingly so in the northwestern portion where this study was conducted. Many parts of the environ- ment are involved, but clearing of the forest and drainage of the land have, perhaps, wrought the most drastic changes. According to Diller (1944), less than four percent of the land in the county remains in forest and this percentage continually declines. Those remnants of woodland which still remain are greatly different from the original forest and they continue to change. Disease has nearly extermi- nated the American elm. Grazing is causing a rapid deterioration of existing mature trees and the complete elimination of reproduction and the understory. Assuming that management does not change, within a few decades there may be almost no timbered tracts remaining. It seems desirable to record what informa- tion can be gathered while it is still available. The work reported here is a portion of a broader study dealing with the history of the natural resources of Van Wert County, Ohio. Van Wert County is particularly interesting, first because it is part of an area which was the last in the state to be settled and developed for agriculture. The changes, therefore, are relatively recent. Secondly, it is an intensively farmed region and, therefore, the magnitude of the change is great.

  • LEVERETT the Amhurstburg Quadrangle but Are Very Scanty Further South
    Open File Report LXI The east border of Lake Rouge is marked by sandy deposits southward from the delta to about 2 miles into FIELD NOTES OF FRANK LEVERETT the Amhurstburg quadrangle but are very scanty further south. There is a very level tract with clay soil and Notebook No. 299 - Leverett scattered boulders over the area below the 600 contour as well as above it. COUNTY There is a slight suggestion of shore work west of Branch Lukerville, 1/8 mile ± from the crossroads with a Chippewa perceptible downward slope to the west and a slight Hillsdale sandy coating. This seems likely to mark the Lake Jackson Rouge limit. The shore is not clearly defined south or Keweenaw southwest from there so it is not feasible to trace it into Keweenaw Peninsula the head of the Big Creek drainage in the way I had Macomb hoped to do. The lake may have extended to within two Mackinac miles of the place where Big Creek is crossed by the Midland & Isabella M.C.R.R. east of the quarries. The valley of Big Creek is Monroe very narrow and sinuous for a mile above the railroad St. Clair bridge but is wider where the creek turns from a N.W. to Washtenaw a S.W. course. There is a wider channel on a small Wayne tributary north from there than on the creek above this OTHER STATES bend. It suggests a spillway coming in from the north. This seems to open out into a feature less plain within a Illinois mile from the bend of Big Creek.
