Saukville is a town in Ozaukee County, Wisconsin, United States. The Village of Saukville is located in the town's southeast quadrant. The population was 1,755 at the 2000 census.
The Mattawa River is a river in central Ontario, Canada. It flows east from Trout Lake east of North Bay and enters the Ottawa River at the town of Mattawa. Counting from the head of Trout Lake, it is 76 km in length. The river's name comes from the Algonquin word for "meeting of waterways".
Lake Passaic was a prehistoric proglacial lake that existed in northern New Jersey in the United States at the end of the last ice age approximately 19,000–14,000 years ago. The lake was formed of waters released by the retreating Wisconsin Glacier, which had pushed large quantities of earth and rock ahead of its advance, blocking the previous natural drainage of the ancestral Passaic River through a gap in the central Watchung Mountains. The lake persisted for several thousand years as melting ice and eroding moraine dams slowly drained the former lake basin. The effect of the lake's creation permanently altered the course of the Passaic River, forcing it to take a circuitous route through the northern Watchung Mountains before spilling out into the lower piedmont.
The Chequamegon–Nicolet National Forest is a 1,530,647-acre (6,194.31 km2) U.S. National Forest in northern Wisconsin in the United States. Due to logging in the early part of the 20th century, very little old growth forest remains. Some of the trees that grow there today were planted by the Civilian Conservation Corps in the 1930s. The national forest lands contain trees and vegetation corresponding to the North Woods Ecoregion that is prevalent throughout the upper Great Lakes region.
The Driftless Area, a region in the American Midwest, comprises southwestern Wisconsin, southeastern Minnesota, northeastern Iowa, and the extreme northwestern corner of Illinois. It was never covered by ice during the last ice age, and therefore lacks glacial deposits, also termed drift. Its landscape is characterized by steep hills, forested ridges, deeply carved river valleys, and karst geology with 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. The steep riverine landscape of both the Driftless Area proper and the surrounding Driftless-like region are the result of early glacial advances that forced preglacial rivers that flowed into the Great Lakes southward, causing them to carve a gorge across bedrock cuestas, thereby forming the modern incised upper Mississippi River valley. The region has elevations ranging from 603 to 1,719 feet at Blue Mound State Park, and together with the Driftless-like region, covers 24,000 square miles (62,200 km2).
Savanna Portage State Park is a state park of Minnesota, USA, established in 1961 to preserve the historic Savanna Portage, a difficult 6-mile (9.7 km) trail connecting the watersheds of the Mississippi River and Lake Superior. The portage trail crosses a drainage divide separating the West Savanna River, which drains to the Mississippi River and the Gulf of Mexico, from the East Savanna River, which flows in an opposite direction to the Saint Louis River, Lake Superior and the Great Lakes, and the Saint Lawrence River to the Atlantic Ocean.
Interstate Park comprises two adjacent state parks on the Minnesota–Wisconsin border, both named Interstate State Park. They straddle the Dalles of the St. Croix River, a deep basalt gorge with glacial potholes and other rock formations. The Wisconsin park is 1,330 acres (538 ha) and the Minnesota park is 298 acres (121 ha). The towns of Taylors Falls, Minnesota and St. Croix Falls, Wisconsin are adjacent to the park. Interstate Park is within the Saint Croix National Scenic Riverway and the Ice Age National Scientific Reserve. The western terminus of the Ice Age National Scenic Trail is on the Wisconsin side. On the Minnesota side, two areas contain National Park Service rustic style buildings and structures that are listed on the National Register of Historic Places.
Lake Duluth was a proglacial lake that formed in the Lake Superior drainage basin as the Laurentide Ice Sheet retreated. The oldest existing shorelines were formed after retreat from the Greatlakean advance, sometime around 11,000 years B.P. Lake Duluth formed at the western end of the Lake Superior basin. Lake Duluth overflowed south through outlets in Minnesota and Wisconsin at an elevation of around 331 m above sea level.
Judge C. R. Magney State Park is a state park in the U.S. state of Minnesota, on the North Shore of Lake Superior. It was named for Clarence R. Magney, a former mayor of Duluth and justice of the Minnesota Supreme Court, who was instrumental in getting 11 state parks and scenic waysides established along the North Shore. The park is best known for the Devil's Kettle, an unusual waterfall and rock formation in which half of the Brule River disappears into a pothole.
Big Bog State Recreation Area, a recent addition to the Minnesota state park system, is located on Minnesota State Highway 72, north of Waskish, Minnesota. It covers 9,459 acres (38.3 km2), primarily swamps, bogs, and upland "islands".
The Bois Brule River is located in Douglas County, Wisconsin, United States, near the county's eastern border with Bayfield County. The river is 43.9 miles (70.7 km) long. The source is in central Douglas County near Upper St. Croix Lake, it flows through the Brule River State Forest, and drains into Lake Superior.
The glacial history of Minnesota is most defined since the onset of the last glacial period, which ended some 10,000 years ago. Within the last million years, most of the Midwestern United States and much of Canada were covered at one time or another with an ice sheet. This continental glacier had a profound effect on the surface features of the area over which it moved. Vast quantities of rock and soil were scraped from the glacial centers to its margins by slowly moving ice and redeposited as drift or till. Much of this drift was dumped into old preglacial river valleys, while some of it was heaped into belts of hills at the margin of the glacier. The chief result of glaciation has been the modification of the preglacial topography by the deposition of drift over the countryside. However, continental glaciers possess great power of erosion and may actually modify the preglacial land surface by scouring and abrading rather than by the deposition of the drift.
The proglacial lakes of Minnesota were lakes created in what is now the U.S. state of Minnesota in central North America in the waning years of the last glacial period. As the Laurentide Ice Sheet decayed at the end of the Wisconsin glaciation, lakes were created in depressions or behind moraines left by the glaciers. Evidence for these lakes is provided by low relief topography and glaciolacustrine sedimentary deposits. Not all contemporaneous, these glacial lakes drained after the retreat of the lobes of the ice sheets that blocked their outlets, or whose meltwaters fed them. There were a number of large lakes, one of which, Glacial Lake Agassiz, was the largest body of freshwater known to have existed on the North American continent; there were also dozens of smaller and more transitory lakes filled from glacial meltwater, which shrank or dried as the ice sheet retreated north.
The Namekagon Portage was a well known canoe portage connecting the St. Croix River watershed to the Chippewa River watershed and was located about five miles south of the present day city of Hayward in Sawyer County, Wisconsin. The portage ran approximately two and one-half miles from the Namekagon River to Windigo Lake in the Chippewa River watershed. The route then proceeded from Windigo Lake through Grindstone Lake to Lac Courte Oreilles where a well known Ojibwa village was located. This portage was used as one of the alternative routes to the Mississippi River for persons passing from Lake Superior to the Mississippi River by way of the Bois Brule River, as described below.
The Cooperrider-Kent Bog State Nature Preserve is state nature preserve located mainly in Kent, Ohio. The preserve surrounds the Kent Bog, a remnant of the Wisconsin Glaciation. It is a true bog with acidic waters and unique environmental conditions have enabled it to survive. The bog contains the largest stand of tamarack trees in the state of Ohio.
The East Savanna River is a small yet historic stream in Aitkin and Saint Louis counties in the U.S. state of Minnesota. With a total length of 15.3 miles (24.6 km), the river rises in Wolf Lake, a small body of water within a spruce bog in Savanna Portage State Park, and flows northeasterly to the Saint Louis River at Floodwood, whence its waters flow to Lake Superior through the Great Lakes and the Saint Lawrence River to the Atlantic Ocean. A few thousand years ago the East Savanna was part of the Mississippi River itself, originating in northeast Minnesota and flowing southwesterly to Big Sandy Lake, from which the great river drained down its present valley to the Gulf of Mexico.
The Grand Portage State Forest is a state forest located near the community of Hovland in Cook County, in extreme northeastern Minnesota. The forest encloses Judge C. R. Magney State Park, Swamp River Wildlife Management Area, Hovland Woods Scientific and Natural Area, and Spring Beauty Hardwoods Scientific and Natural Area. It borders the Grand Portage Indian Reservation to the east, the Superior National Forest to the west, and Ontario to the north. The forest is named after the Grand Portage, a historic trade route between the Great Lakes and the Northwest.
The Eshqua Bog Natural Area is a protected area in Hartland, Vermont. It is 41 acres containing a wet bog. It is near Woodstock, about 11 miles west of White River Junction. There is a boardwalk allowing access to the wetland and views of rare plants.
Grandma Lake Wetlands State Natural Area is a Wisconsin Department of Natural Resources-designated State Natural Area featuring the undeveloped, pristine 44-acre Grandma Lake, which lies in a depression formed during the last glacial period. The lake is ringed by a large, open sphagnum bog mat. The bog mat is surrounded by a coniferous swamp of tamarack and black spruce. The bog mat supports a plant community that is considered diverse and unusual, with several rare species present, including: bog arrow-grass, dragon's mouth orchid, livid sedge, small-headed bog sedge, as well as one of only a few known populations of bog rush in the State of Wisconsin. In 1991, the US Forest Service designated the site as a Research Natural Area. Also, the site is listed as one of Wisconsin's Wetland Gems, by the Wisconsin Wetlands Association.
Kiser Lake Wetlands State Nature Preserve, or simply Kiser Lake Wetlands, is a 51 acres (21 ha) nature reserve located in Johnson Township, Champaign County, Ohio, United States. It is located wholly within the Kiser Lake State Park, and operated by the Ohio Department of Natural Resources.
