Wisconsin's Henry S Reuss Ice Age Visitor Center: Kettle Moraine State Forest Northern Headquarters

The Henry S. Reuss Ice Age Visitor Center has exhibits on Wisconsin's Ice Age Parks and Trail. It is the Kettle Moraine State Forest Northern Unit headquarters.

The Ice Age Visitor Center

The Ice Age Visitor Center has the welcoming look of glassy expanses, modern design, and stone exterior. It invites inside all those curious or knowledgeable about the impact of 100,000 super-cold years upon the landscape. It offers exhibits as well as the 20+/-minute info-film "The Night of the Sun" most excellently narrated by esteemed actor Eli Herschel Wallach (born December 7, 1915).

Peak season hours occur from April through October. The Ice Age Visitor Center opens from 8:30 a.m. to 4:00 p.m. Monday through Friday and from 9:30 a.m. until 5:00 p.m. on weekends. Variable hours prevail from November through March.

Half a mile west of Dundee on Highway 67 takes visitors to the Ice Age Visitor Center, with the physical address of N1765 Hwy G Campbellsport, WI 53010, and the telephone number of (920) 533-8322.

The Exhibit Room in the Ice Age Visitor Center introduces visitors to four successively advancing and retreating 1-mile (1.61-kilometer) thick ice sheets which covered one-third of Planet Earth's surface. The sheets occurred when snow accumulation remained after warm-weather melts. They took place following worldwide cooling of 1+ million years ago.

The last Ice Age began 110,000 years ago. It peaked 18,000 years ago. The final thaw took place 12,000 to 10,000 years ago.The last stage was named the Wisconsin Glacial Age. It was preceded by the Illinoian, Kansan and Nebraskan glaciations.

Horicon Marsh, migratory/nesting area for millions of waterfowls: 32,000 acres (130 km2); one of USA's largest freshwater wetlands, with 3 ecological zones (marsh and peat areas; small pothole wetlands; shallow lakes); national and state wildlife refuge

Each glaciation changed the landscape north of Cross Plains. The village is the glacier's stopping point. It therefore lacks such glaciated hallmarks as:

Glacial melt-water carving Interstate State Park's river gorge and potholes;
Stagnant glacier melt-water dropping debris throughout the Chippewa Moraine's cracked surface;
Horicon Marsh's glacially-created lake;
Glacial melt encouraging the growth of a young spruce forest, which was overturned, killed and buried under 12 to 15 feet (3.66 to 4.57 meters) of clay and rocks in Two Creeks Buried Forest;
Water, wind and winter ice eroding the insular remains from a glacial lake into Mill Bluff State Park's southwestern-style sandstone buttes;
Glaciers forming Devil's Lake State Park's 500-foot (152.4-meter) high bluffs and spectacular lake;
Ice on the move leaving large, long hills (drumlins) in the Campbellsport area around the center;
Rock debris of the Continental Ice Sheet's westward-moving Lake Michigan lobe mixing with the eastward-moving Green Bay lobe.

Drumlins, Eskers, Kames, Kettles, Moraines, and Outwashes

The word drumlins comes from the ancient Irish Gaelic for the ridge of a hill. Drumlins form into long, narrow mounds of clay and rock. They have the teardrop shape of one rounded end and one tapered. The narrow end indicates the direction of ice flow.

The word eskers comes from the ancient Irish Gaelic for a ridge separating two plains. These long, winding gravelly ridges cross rolling landscapes. They identify places where water flowed through tunnels within the stagnant ice.The best known of Wisconsin's eskers is the Parnell Esker accessible by the Ice Age and Parnell Tower Trails.

Irregular shape of kames was formed by sand and gravel left behind by retreating glaciers.

The Scots word kame designates cone-shaped, steep-sided hills. Kames form from water falling through vertically-fractured shafts in ice. The water moves debris from above to below ground. Gravel and sand remain when the long-stagnant glacier melts. Many kames stand
100+ feet (30.48+ meters) tall. Kames and kettles typify Kettle Moraine State Forest's landscape.

Scientists review satellite images of lakes, including glacial kettle lakes, to assess water clarity across the state of Wisconsin.

Kettles are depressions which pock the landscape. They form from the melting of ice blocks buried deep within rubbled surfaces. They measure 12 feet (3.66 meters) to 2+ miles 3218.69+-meters) in diameter. Some depressions remain dry. Others will accumulate water, to become lakes and ponds, such as Bear and Greenbush Kettle Lakes.

Formerly a gorge of the Wisconsin River, Devil's Lake was created by moraine damming of its southeastern and northern ends during the advance of the Wisconsinan ice sheet, about 85,000-11,000 years ago.

The word moraine comes from the Vulgate Latin murrum for "round object." Moraines jumble loose rocks and soil assumed and abandoned by active glaciers. End moraines look ridge-like, such as the Kettle Moraine. Ground moraines measure 2 inches (5.08 centimeters) to 100+ feet (30.48+ meters).

Outwashes are level plains. They form from the moving of gravel and ice by glacial melt. Melt-water moves in broad, shallow channels. It stops pushing boulders, clay, gravel, sand or silt once its momentum slows. One consequence will be built-up rich farmland, as in the Jersey Flats area of Lake Winnebago.

Kettle Moraine State Forest

Lapham Peak Unit; Loew Lake Unit

Kettle Moraine State Forest is in southeastern Wisconsin. It is known for glacial landforms and hilly terrain. It spreads 100 miles (160,934.4 meters) over five units.

The Lapham Peak Unit lies south of Delafield, in Washington County. It offers hiking trails and an observation tower.

The Loew Lake Unit of Washington County includes a small recreation area in the town of Erin on the Oconomowoc River. It offers hiking, horse riding, and hunting.

Northern Unit

The northern unit extends from near Glenbeulah in the north to near Kewaskum in the east. It goes into Fond du Lac, Sheboygan and Washington Counties. It includes:

Kettle Moraine State Forest headquarters;
Greenbush, Long Lake and Mauthe Recreation Areas;
Parnell Observation Tower;
Spruce Lake Bog (State Natural Area No. 59).

Kettle Moraine State Forest's Pike Lake Unit is named for its 522-acre kettle lake; Powder Hill, 1,350-foot (411.48 meter) kame, with 65–foot (19.8 meter) tower, overlooks heart-shaped Pike Lake.

Kettle Moraine State Forest and Ice Age National Scenic Trail

All units can be accessed through the Ice Age Trail of the glacier's furthest advance into Wisconsin during the last Ice Age. In 1980 and by the National Trails Systems Act (Public Law 90 543, 1968), Congress designated the trail a national scenic trail to be protected for its natural beauty. The designation reminds everyone of the efforts of:

Milwaukee businessman Raymond T. Zillmer (1887-1960), Ice Age Park & Trail Foundation founder (1958) of the subsequent Ice Age Trail Alliance, Inc.;
Congressman Henry Schoellkopf Reuss (February 22, 1912-January 12, 2002), author of On the Trail of the Ice Age (1976);
James J. Staudacher (born 1958), Shorewood native and first backpacker to complete 1,000 trail miles (1,609.3 kilometers), summer 1979.

Parnell Tower

Parnell Tower can be accessed by vehicle or on foot. It is accessible by the county highway intersection with Kettle View Drive. It also may be accessed by biking, cross-country skiing, hiking, horseback riding, and snowmobiling trails. Additionally, its access overlaps with the Ice Age Trail near backpack camping shelter number 4.

Between the entrance and the tower is the parking area. Visitors may choose to access drinking water, facilities, grills, or picnic tables before heading to the tower. The hike will take no more than what the individual or group needs to walk about 1/4 mile (0.4 kilometer) if the route is taken strictly to make the round-trip of parking lot-tower-parking lot.

autumn's splendid vista from top of Parnell Tower: when walking the tower's trail, this dense canopy of red oaks (Quercus rubra) and maples (Acer rubrum) obscures the tower from view, despite its location on the Northern Unit's highest elevation.

The tower affords the highest point of elevation -- 1,311 feet (399.59 meters) -- within the forest's northern unit. It began its life as a fire lookout tower for early reporting and extinguishing of wildfires. But it now functions as a scenic observation tower for state forest visitors.The tower's wood structure measures a total of 60 feet (18.29 meters). It offers a 25-mile (40.23-kilometer) view from all sightseeing perspectives on clear days. The view will convey to visitors the general economic use which glaciated landscapes have for Wisconsinites: development of farmland and growth of deciduous and pine forests.

The view from the tower often inspires visitors to take time out for the Parnell Tower hiking trail. The hiking trail loops 3.5 miles (5.63 kilometers) through woodlands characterized by abundantly and densely growing red maple (Acer rubrum) and red oak (Quercus rubra) trees. The tower trail provides views of the forest's pine (Pinus spp) plantation to the north and of the forest's marshes and swamps to the northwest. The trail supplies visitors with frequent sightings of red squirrels (Sciurus vulgaris), turkeys (Mealeagris gallopavo), and white-tailed deer (Odocoileus virginianus).

Dundee, Wisconsin

The Ice Age Center can be accessed from Wisconsin Highway 67. It is in Campbellsport, near the
unincorporated community of Dundee. Dundee is located within the town of Osceola. Osceola is named after Florida Seminole Chief Osceola (Creek Asi-yahola [English: "yaupon holly ceremonial black drink" + "shouter"]), who was born Billy Powell (1804-January 30, 1838) in Talisi (Tallassee), Alabama to English trader William Powell and Polly Coppinger of Creek Native American and Scots-Irish parentage.

Osceola's first permanent European settlers probably arrived in 1845. In February 1854, E.M. McIntosh platted, recorded and named Dundee (Celtic: Dùn Dè; English: "fort" + "fire"), in honor of the city in Scotland. In 1855, he and Stephen Palmer put the finishing touches on Dundee's first dam and sawmill. By 1858, a flouring mill was functional thanks to William and Leroy Palmer. By 1880, there were Catholic, Lutheran and Reformed churches; a post office; and the business opportunities of the Brokmeyer cattle fair and Dundee Hotel.

Dundee and Osceola are known for scenery and wildlife. Both give excellent views of Dundee Mountain, to the northeast. Additionally, Dundee is located within Kettle Moraine State Forest-Northern Unit, which includes the Ice Age Center. Through Dundee also passes the 115-mile (185.07-kilometer) Kettle Moraine Scenic Drive.

The drive begins in the Whitewater area of Jefferson and Walworth Counties and ends northwest of Elkhart Lake in Sheboygan County's Broughton Marsh Park. It mainly consists of county and local roads. It is intended to link the state forest's northern and southern units. In order to do so, it passes through the Wisconsin counties of:

Fond du Lac;
Jefferson;
Sheboygan;
Walworth;
Washington;
Waukesha.

The visit to Dundee therefore can be the charmed starting-point and the picturesque ending-point to adventures into Wisconsin's super-cold past through forays into Ice Age-related centers, drives, natural areas, and trails.
