"Do Not Eat" Fish & "Avoid Foam" Advisories
Residents should continue following 'Do Not Eat' and 'Avoid Foam' advisories for Huron River and several nearby waterbodies More fish tissue and surface water data needed before advisories can be relaxed FOR IMMEDIATE RELEASE July 2, 2020 Contact: Lynn Sutfin, 517-241-2112 LANSING, Mich.- With the summer recreation season in full swing, the Michigan Department of Health and Human Services (MDHHS) is issuing a reminder that everyone should avoid eating fish from the Huron River and several connected waterbodies, and avoid foam on Michigan lakes and rivers known to have per- and polyfluoroalkyl substances (PFAS) in the water. “MDHHS advises residents to continue following the ‘Do Not Eat’ fish and the ‘Avoid Foam’ advisories in place for the Huron River,” said Dr. Joneigh Khaldun, chief medical executive and chief deputy for health at MDHHS. “Both advisories remain in effect until scientific evidence indicates that advisories are no longer necessary.” Fish Advisory The “Do not Eat” fish advisory is based on perfluorooctane sulfonate (PFOS) fish data from the Michigan Department of Environment, Great Lakes, and Energy (EGLE). In 2018, high PFOS levels were found in fish filets collected from Kent Lake, Base Line Lake and Argo Pond. Additionally, high PFOS surface water levels were found from Norton Creek downstream to Barton Pond. In August 2018, MDHHS issued a ‘Do Not Eat’ advisory for fish from the Huron River where North Wixom Road crosses into Oakland County to the mouth of the Huron River as it enters Lake Erie in Wayne County.

The Evolution of Crayfishes of the Genus Orconectes Section Limosus (Crustacea: Decopoda)
THE OHIO JOURNAL OF SCIENCE Vol. 62 MARCH, 1962 No. 2 THE EVOLUTION OF CRAYFISHES OF THE GENUS ORCONECTES SECTION LIMOSUS (CRUSTACEA: DECOPODA) RENDELL RHOADES Department of Zoology and Entomology, The Ohio State University, Columbus 10 The earliest described crayfish species now included in the Section limosus of the Genus Orconectes was described by Samuel Constantine Rafinesque (1817: 42). He reported the species, which he named Astacus limosus, "in the muddy banks of the Delaware, near Philadelphia." How ironical it now seems, that when Rafinesque located at Transylvania three years later and traveled to Henderson, Kentucky, to visit a fellow naturalist, John J. Audubon, he could have collected from the streams of western Kentucky a crayfish that he might have identified as the species he had described from the Delaware. We now know that these streams of the knobstone and pennyroyal uplands are the home of parent stock of this group. Moreover, this parental population on the Cumberland Plateau is now separated from Rafinesque's Orconectes limosus of the Atlantic drainage by more than 500 miles of mountainous terrain. Even Rafinesque, with his flair for accuracy and vivid imagination, would have been taxed to explain this wide separation had he known it. A decade after the death of Rafinesque, Dr. W. T. Craige received a blind crayfish from Mammoth Cave. An announcement of the new crayfish, identi- fied as "Astacus bartonii (?)" appeared in the Proceedings of the Academy of Natural Science of Philadelphia (1842: 174-175). Within two years the impact of Dr. Craige's announcement was evidenced by numerous popular articles both here and abroad. -
Upper Neogene Stratigraphy and Tectonics of Death Valley — a Review

Bureau of Reclamation, P. O. Box 25007, D-8530, Denver, CO 80225-0007, United States Abstract New tephrochronologic, soil-stratigraphic and radiometric-dating studies over the last 10 years have generated a robust numerical stratigraphy for Upper Neogene sedimentary deposits throughout Death Valley. Critical to this improved stratigraphy are correlated or radiometrically-dated tephra beds and tuffs that range in age from N3.58 Ma to b1.1 ka. These tephra beds and tuffs establish relations among the Upper Pliocene to Middle Pleistocene sedimentary deposits at Furnace Creek basin, Nova basin, Ubehebe–Lake Rogers basin, Copper Canyon, Artists Drive, Kit Fox Hills, and Confidence Hills. New geologic formations have been described in the Confidence Hills and at Mormon Point. This new geochronology also establishes maximum and minimum ages for Quaternary alluvial fans and Lake Manly deposits. Facies associated with the tephra beds show that ~3.3 Ma the Furnace Creek basin was a northwest–southeast-trending lake flanked by alluvial fans. This paleolake extended from the Furnace Creek to Ubehebe. Based on the new stratigraphy, the Death Valley fault system can be divided into four main fault zones: the dextral, Quaternary-age Northern Death Valley fault zone; the dextral, pre-Quaternary Furnace Creek fault zone; the oblique–normal Black Mountains fault zone; and the dextral Southern Death Valley fault zone. -

MAPPING AND CHARACTERIZING A RELICT LACUSTRINE DELTA IN CENTRAL LOWER MICHIGAN By Christopher B. Connallon A THESIS Submitted to Michigan State University in partial fulfillment of the requirements for the degree of Geography – Master of Science 2015 ABSTRACT MAPPING AND CHARACTERIZING A RELICT LACUSTRINE DELTA IN CENTRAL LOWER MICHIGAN By Christopher B. Connallon This research focuses on, mapping and characterizing the Chippewa River delta - a sandy, relict delta of Glacial Lake Saginaw in central Lower Michigan. The delta was first identified in a GIS, using digital soil data, as the sandy soils of the delta stand in contrast to the loamier soils of the lake plain. I determined the textural properties of the delta sediment from 142 parent material samples at ≈1.5 m depth. The data were analyzed in a GIS to identify textural trends across the delta. Data from 3276 water well logs across the delta, and from 185 sites within two-storied soils on the delta margin, were used to estimate the thickness of delta sands and to refine the delta's boundary. The delta heads near Mount Pleasant, expanding east, onto the Lake Saginaw plain. It is ≈18 km wide and ≈38 km long and comprised almost entirely of sandy sediment. As expected, delta sands generally thin away from the head, where sediments are ≈4-7m thick. In the eastern, lower portion of the delta, sediments are considerably thinner (≈<1-2m). The texturally coarsest parts of the delta are generally coincident with former shorezones. The thick, upper delta portion is generally coincident with the relict shorelines of Lakes Saginaw and Arkona (≈17.1k to ≈ 16k years BP), whereas most of the thin, distal, lower delta is generally associated with Lake Warren (≈15k years BP). -

Cammerer, Director UNITED STATES GOVERNMENT PRINTING OFFICE, WASHINGTON EATH VALLEY National Monument was created by Presidential proclamation on 2February 11), 1933, and enlarged to its present dimensions on March 26, 1937. Embracing 2,981 square miles, or nearly 2 million acres of primitive, unspoiled desert country, it is the second largest area administered by the National Park Service in the United States proper. Famed as the scene of a tragic episode in the gold-rush drama of '49, Death Valley has long been known to scientist and layman alike as a region rich in scientific and human interest. Its distinctive types of scenery, its geological phenomena, its flora, and climate are not duplicated by any other area open to general travel. In all ways it is different and unique. The monument is situated in the rugged desert region lying east of the High Sierra in eastern California and southwestern Nevada. The valley itself is about 140 miles in length, with the forbidding Panamint Range forming the western wall, and the precipitous slopes of the Funeral Range bounding it on the east. -
North Ridge Scenic Byway Geology
GUIDE TO THE NORTH RIDGE SCENIC BYWAY GEOLOGY LANDFORMS The North Ridge Scenic Byway corridor lies in the Erie Lake Plain landform of the Central Lowlands Physiographic Province of the United States (Fenneman 1938; Brockman 2002). The Lake Plain consists of wide expanses of level or nearly level land interrupted only by sandy ridges that are remnants of glacial-lake beaches and by river valleys carved into Paleozoic bedrock. With the exception of the sandy ridges, much of the Lake Plain in Avon and Sheffeld was a dense swamp forest prior to settlement. The North Ridge Scenic Byway follows the northernmost ancient beach ridge as it traverses Sheffeld and Avon at an elevation ranging from 675 to 690 feet above sea level, some 105 to 120 feet above modern Lake Erie. Topography of Sheffeld and Avon Townships as surveyed in 1901, showing North Ridge near the center of the map (courtesy of U.S. Geological Survey, Oberlin, Ohio Quadrangle 1903). 2 GEOLOGY FORMATION OF NORTH RIDGE Approximately 18,000 years ago, the last The chronology of lake stages in the Lake continental glacier blanketed northern Ohio as Erie basin relates a fascinating story of glacial it pushed down from the north to its maximum action, movements of the earth’s crust and southern thrust. The ice sheet reached as far erosion by waves to form the body of water south as Cincinnati, Ohio, then it began to we see today. The story begins nearly 15,000 melt back. As the glacier paused in its retreat, years ago as the last glacier [known as the piles of rock and clay debris [known as end Wisconsinan ice sheet] temporarily halted to moraines] were built up at the ice margins. -

DISTRIBUTION AS A FUNCTIONAL FACTOR OF ROCK ALIGNMENTS IN THE MOJAVE DESERT Jay Von Werlhof Imperial Valley College Desert Museum El Centro, California ABSTRACT This paper suggests that the distribution, setting, content, and form of early rock alignments in the Mojave Desert are directly related to the function of these features. Each of these factors will be described and discussed in turn, leading to an interpretive synthesis. Why a reliable model cannot be developed for locating rock alignment sites is also suggested. I am pleased to have been invited to present a paper in this noted also that a few isolated sites are uniquely present, which session honoring Dee Simpson. I have admired her life-long is another concern of research. Such sites, for example, might devotion to archaeology and the tenacity with which she works have been in the process of being developed into larger and toward goal completions. I am also indebted to her, along more complex sites but were never completed, as possibly that with Arda Haenzel, her co-worker at the San Bernardino at Lavic Lake (MacDonald 1993). Also, in complex sites con County Museum, for interesting me in earthen art back in taining numerous designs it is not clear whether the diverse el 1975 when few others thought that path worth treading. Since ements are even temporally related, or if each design exists as then, I have worked to advance the study of geogylphs and rock an entity from a different era. However, this type of earthen art alignments, and the paper I am presenting today is drawn appears to have been the earliest, and its association with the around a small sector of that study: distribution as a functional Lake Hill Pleistocene site (Davis 1978) focuses the Panamint factor of rock alignments in the Mojave Desert.
