Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals.
The Driftless Area, also known as Bluff Country and the Paleozoic Plateau, is a topographical and cultural region in the Midwestern United States that comprises southwestern Wisconsin, southeastern Minnesota, northeastern Iowa, and the extreme northwestern corner of Illinois. The Driftless Area is a USDA Level III Ecoregion: Ecoregion 52. The Driftless Area takes up a large portion of the Upper Midwest forest–savanna transition. The Blufflands refers to the eastern section of the Driftless area in Minnesota, due to the steep bluffs and cliffs around the river valleys. The western half is known as the Rochester Plateau, which is flatter than the Blufflands. The Coulee Region refers to the southwestern part of the Driftless Area in Wisconsin. It is named for its numerous ravines.
Devil's Lake State Park is a state park located in the Baraboo Range in eastern Sauk County, just south of Baraboo, Wisconsin. It is around thirty-five miles northwest of Madison, and is on the western edge of the last ice-sheet deposited during the Wisconsin glaciation. The state park encompasses 9,217 acres (3,730 ha), making it the largest in Wisconsin. The state park is known for its 500-foot-high (150 m) quartzite bluffs along the 360-acre (150 ha) Devil's Lake, which was created by a glacier depositing terminal moraines that plugged the north and south ends of the gap in the bluffs during the last ice age approximately 12,000 years ago. The sand at the bottom of Devil's Lake is thought to be deposited by glaciers.
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.
The Kettle Moraine State Forest is a state forest in southeastern Wisconsin. The chief feature of the reserve is the Kettle Moraine, a highly glaciated area. The area contains very hilly terrain and glacial landforms, such as kettles, kames and eskers. The 56,000-acre (23,000 ha) forest is divided into two large and three small units, which are spread across a hundred miles.
Horicon Marsh is a marsh located in northern Dodge and southern Fond du Lac counties of Wisconsin. It is the site of both a national and a state wildlife refuge. The silted-up glacial lake is the largest freshwater cattail marsh in the United States.
Rib Mountain State Park is a 1,528-acre (618 ha) Wisconsin state park near the city of Wausau. The park includes a ski resort, Granite Peak Ski Area, concession stand, picnic areas, a reservable amphitheater, a former quarry, observation tower, and 15.1 miles of trails. The park is ten miles (16 km) north-northwest of Central Wisconsin Airport.
Whitefish Dunes State Park is a 867-acre (351 ha) state park of Wisconsin on the eastern shore of the Door Peninsula. This day-use park preserves the most substantial sand dunes on the western shore of Lake Michigan. The remains of eight successive prehistoric Native American villages are on the National Register of Historic Places as Whitefish Dunes-Bay View Site. Cave Point County Park is an enclave inside the state park, allowing visitors free foot access to the state park by the shoreline trail connecting the parks.
The Badger Army Ammunition Plant or Badger Ordnance Works (B.O.W.) is an excess, non-BRAC, United States Army facility located near Sauk City, Wisconsin. It manufactured nitrocellulose-based propellants during World War II, the Korean War, and the Vietnam War. It was a large munitions factory during World War II. As of 2013, the facility was in the end stages of demolition and remediation in preparation for property transfer.
Lake Louise is a glacial lake within Banff National Park in Alberta, Canada. Situated 11 km (6.8 mi) east of the border with British Columbia, Lake Louise is located 5 km (3.1 mi) west of the hamlet of Lake Louise and the Trans-Canada Highway.
The Baraboo Range is a syncline located in Columbia and Sauk Counties, Wisconsin. It consists of highly eroded Precambrian metamorphic rock. It is about 25 miles (40 km) long and varies from 5 to 10 miles (16 km) in width. The Wisconsin River, previously traveling in a north to south direction, turns to the east just north of the range before making its turn to the west towards the Upper Mississippi River. The eastern end of the range was glaciated during the Wisconsinian glaciation, while the western half was not, and consequently, marks the eastern boundary of Wisconsin's Driftless Area.
Wisconsin, a state in the Midwestern United States, has a vast and diverse geography famous for its landforms created by glaciers during the Wisconsin glaciation 17,000 years ago. The state can be generally divided into five geographic regions—Lake Superior Lowland, Northern Highland, Central Plain, Eastern Ridges & Lowlands, and Western Upland. The southwestern part of the state, which was not covered by glaciers during the most recent ice age, is known as the Driftless Area. The Wisconsin glaciation formed the Wisconsin Dells, Devil's Lake, and the Baraboo Range. A number of areas are protected in the state, including Devil's Lake State Park, the Apostle Islands National Lakeshore, and the Chequamegon–Nicolet National Forest.
Kohler-Andrae State Park comprises two adjacent Wisconsin state parks located in the Town of Wilson, a few miles south of the city of Sheboygan. They are managed as one unit. Terry Andrae State Park, established in 1927, and John Michael Kohler State Park, established in 1966, total 988 acres (4.00 km2). The parks contain over two miles (3 km) of beaches and sand dunes along the shore of Lake Michigan, with woods and wetlands away from the water. The Black River flows through the parks.
Pewit's Nest State Natural Area is a nature reserve in Wisconsin, USA, that includes a deep gorge formed during the retreat of the last glacier. Pewit's Nest is outside Baraboo in Sauk County. At one time a waterwheel and mill were located on the site and an individual lived in the solid sandstone. The name of the site was a result of early settlers calling it "Peewit's Nest" after the abode, ten feet above a deep pool of water, resembling the nest of a phoebe. The water-wheel once turned lathes for repairing or manufacturing equipment, but no evidence of it remains. Pewit's Nest is owned by the Wisconsin Department of Natural Resources and was designated a State Natural Area in 1985.
Castle Rock Lake is an artificial lake on the Wisconsin River. It is located in central Wisconsin in Adams County and Juneau County. The lake has an inflow from Petenwell Lake, Yellow River, Big Roche a Cri., and Klien Creek. It has a surface area of 16,640 acres (67.3 km2) and its depth varies from 8–20 ft (2.4–6.1 m) in most places, with area in the old river beds reaching as deep as 35 ft (11 m).
The Turtle-Flambeau Flowage is a 12,942 acres (52.37 km2) lake in Iron County, Wisconsin. It has a maximum depth of 15 meters and is the seventh largest lake in the state of Wisconsin by surface area. The flowage is home to unique wetland patterns and plant species as well as several species of sport and game fish, including Musky, Panfish, Largemouth Bass, Smallmouth Bass, Northern Pike, Walleye and Sturgeon. The lake's water clarity is low, but can vary in different locations in the lake. Fishing, camping, boating, and hunting are popular activities on the flowage, and Ojibwe people traditionally harvest fish and game on the lake. Environmental concerns on the flowage include mercury contamination, algal blooms, and several types of invasive species.
Parfrey's Glen, located within Devil's Lake State Park, is a Wisconsin Department of Natural Resources-designated State Natural Area. The glen is a deep gorge cut through the sandstone of the south flank of the Baraboo Hills. It was the first State Natural Area to be designated in Wisconsin. The valley was named for Robert Parfrey.
Baraboo Quartzite is a Precambrian geological formation of quartzite, found in the region of Baraboo, Wisconsin. While pure quartzite is usually white or gray, Baraboo Quartzite is typically dark purple to maroon in color, due to the presence of iron (hematite) and other impurities. Baraboo Quartzite may display strata created by progressive deposition of layers of sand in the original sandstone from which the quartzite was formed. Specimens of Baraboo quartzite may also display ripple marks that appear visually similar to the patterns one might see in the sand at a beach. Ripples indicate that the sandstone from which the quartzite was metamorphosed was originally water-laid sediment.
The Southern Unit of the Kettle Moraine State Forest includes more than 22,000 acres of land throughout southern Wisconsin and spans several state parks and natural areas. The area also features varied environments from restored prairie, forests, and lakes, along with providing a multitude of recreational opportunities such as hiking, birdwatching, fishing, camping, and hunting. The Kettle Moraine Scenic Drive also extends within this region as well as through a larger portion of the state.
Ableman's Gorge is a 127 acres (51 ha) Wisconsin State Natural Area located near Rock Springs, Wisconsin. This 200 to 400-foot wide and 200-foot high gorge is cut by about 1 mile (1.6 km) of the Baraboo River in an "L" shape. The Natural Area is named after Stephen Van Rensselaer Ableman, who settled Rock Springs in 1851 and named the community after the gorge area.
