61 Pleistocene Lake Mojave Stratigraphy And
HISTORY, PROCBSS, AND TRADITION: it SYMPOSIUM FOR MAKOTO KOnA 61 PLEISTOCENE LAKE MOJAVE STRATIGRAPHY AND ASSOCIATED CULTURAL MATERIAL CLAUDE N. WARREN AND JOAN S. SCHNEIDER The problems of geoarchaeology addressed in this paper were probably most clearly stated very early in the research, almost 40 years ago (Warren and DeCosta 1964). To adequately date the artifact assemblages from the 24 "surface sites" on the high beach lines of Pluvial Lake Mojave, two tasks must be successfully completed: (1) construct the geomorphic history of Lake Mojave from the strafigraphy, topographic re/afionships, radiocarbon dates, and any other useful data, and (2) demonstrate the stratigraphic relationship between prehistoric artifacts and lacustrine deposits of Lake Mojave. These two tasks are addressed in this paper, demonstrating the sequence of beach-ridge INTRODUCTION formation at Lake Mojave (Antevs 1937; Ore and Warren 1971; Wells et al. 1989). Additional data The Mojave River periodically flowed into from other locations within the range of elevations Death Valley during the late Pleistocene and early of the high beach ridges are integrated with Holocene.

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). -

Quagga Mussels Threaten Western U.S. Waters, Researcher Reports 1 July 2008
Quagga mussels threaten western U.S. waters, researcher reports 1 July 2008 and are out-competing zebra mussels, O'Neill told the House committee. Last year, quaggas were discovered for the first time in the West in Nevada's Lake Mead and have since been found down the Colorado River in Lake Mojave, Lake Havasu and in various locations in California. "[The spread west] is not a surprise," said O'Neill. "It's something that's been expected to happen." Both quagga and zebra mussels originated in Eurasia in the Caspian, Ural and Baltic seas and spread to the United States in ballast water from Both quagga, pictured, and zebra mussels originated in freighters.

Spatial variation in till texture and clay mineralogy across the Saginaw Lobe terrain, Great Lakes region, USA Department of Geography, Environment and Spatial Sciences, Randall J. Schaetzl, Chris Baish, Jarrod Knauff, Thomas Bilintoh, East Lansing, Michigan, USA Dan Wanyama, Kevin McKeehan, and Michelle Church Abstract STUDY AREA SAMPLE DISTRIBUTION Great Lakes region We present a spatial/mapping approach to the study of the glacial history of the Saginaw lobe of the Laurentide Ice Sheet. The Saginaw Lobe flowed into southern Michigan, USA, forming modern-day Saginaw Bay and leaving behind a series of small moraines in down- ice locations. Upon its retreat – and likely also during its advance – a large proglacial lake (Glacial Lake Saginaw) formed in the northeastern margins of the “Saginaw terrain”. The Saginaw lobe advanced to the southwest, out of this lake basin and onto thinly mantled, sandstone and shale bedrock. Although the Late Pleistocene deglacial chronology of this lobe has been generally assumed for decades, few numerical ages exist that could help constrain a better defined timeline. Indeed, as luminescence ages slowly emerge for terrain of the Saginaw Lobe and nearby areas, it seems clear that the lobe retreated from the region considerably earlier than is generally assumed, adding to the potential for large areas of ponded water in proglacial settings, all of which are as yet unmapped. In this project, we sampled tills on uplands across the terrain of the Saginaw Lobe, avoiding outwash plains. In all, we obtained 334 samples of calcareous till, by bucket auger. Sample locations were sited generally uniformly across >20,000 km2. -

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. -

Geology of Michigan and the Great Lakes
35133_Geo_Michigan_Cover.qxd 11/13/07 10:26 AM Page 1 “The Geology of Michigan and the Great Lakes” is written to augment any introductory earth science, environmental geology, geologic, or geographic course offering, and is designed to introduce students in Michigan and the Great Lakes to important regional geologic concepts and events. Although Michigan’s geologic past spans the Precambrian through the Holocene, much of the rock record, Pennsylvanian through Pliocene, is miss- ing. Glacial events during the Pleistocene removed these rocks. However, these same glacial events left behind a rich legacy of surficial deposits, various landscape features, lakes, and rivers. Michigan is one of the most scenic states in the nation, providing numerous recre- ational opportunities to inhabitants and visitors alike. Geology of the region has also played an important, and often controlling, role in the pattern of settlement and ongoing economic development of the state. Vital resources such as iron ore, copper, gypsum, salt, oil, and gas have greatly contributed to Michigan’s growth and industrial might. Ample supplies of high-quality water support a vibrant population and strong industrial base throughout the Great Lakes region. These water supplies are now becoming increasingly important in light of modern economic growth and population demands. This text introduces the student to the geology of Michigan and the Great Lakes region. It begins with the Precambrian basement terrains as they relate to plate tectonic events. It describes Paleozoic clastic and carbonate rocks, restricted basin salts, and Niagaran pinnacle reefs. Quaternary glacial events and the development of today’s modern landscapes are also discussed. -
Is There Any Evidence of Mega-Lake Manly in the Eastern Mojave Desert During Oxygen Isotope Stage 5E/6?
Quaternary Research 57, 177–179 (2002) doi:10.1006/qres.2001.2299, available online at http://www.idealibrary.com on REPLY Is There Any Evidence of Mega-Lake Manly in the Eastern Mojave Desert during Oxygen Isotope Stage 5e/6? I am pleased to have the opportunity to defend and clarify the implication that Ku’s dates are more reliable than those of my hypothesis regarding the extent of the Blackwelder stand of Hooke and Lively (see Hooke and Dorn, 1992) is debatable, Lake Manly during marine oxygen isotope stage 6 (OS6). Let given that both use the -counting technique and thus may suffer me start by addressing a couple of general points. from problems with U migration. First, with reference to the pejorative prefix “mega” in Enzel Salt Spring Hills shoreline. Enzel et al. maintain that this et al.’s comment, let me put the size of the lake under discussion shoreline is cut into colluvium and, at its southeastern end, into in perspective. If water were to fill Death Valley to the 90-m alluvial fan deposits. I agree with the former. On the other hand, level today, the surface area would be 1600 km2 (Meek, 1997), air photos, a map in Anderson and Wells (1997), and my own whereas the area Hale proposed, based on overflow at Ash Hill observations do not support the interpretation that it is cut into an pass, would have been 8000 km2 (Hale, 1985). The surface alluvial fan at its southeastern end. Even if further study shows area of the OS6 lake proposed in my paper is 2800 km2, less that it is, however, Enzel et al.’s statements about the age of than half the size of Hale’s lake and less than twice the size a the fan unit are misleading (1) because they are based on dates 90-m lake would have were it to occupy the valley today. -

Since then, archaeologists have cited Rogers' publication and repeated his claim that such a pueblo was located in the Western Mojave Desert. The purpose of this thesis started out as a review of the existing evidence and to locate this pueblo.
