Ice Age

National Scenic Trail - Wisconsin

The Ice Age Trail is a National Scenic Trail stretching 1,200 miles (1,900 km) in the state of Wisconsin. The trail roughly follows the location of the terminal moraine from the last Ice Age. As the route traverses the moraine, it sometimes meanders into areas west of the moraine, including the Driftless Area in southwestern Wisconsin. The trail passes through 30 of Wisconsin's 72 counties, from the northwestern part of the state to the Lake Michigan shoreline in the east. The western end of the trail is at Interstate State Park along the St. Croix River, which is the border between northwestern Wisconsin and eastern Minnesota. The eastern terminus of the Ice Age Trail lies at Potawatomi State Park, along Wisconsin's Door Peninsula off of Sturgeon Bay.

Wisconsin's Glacial Landscape A mere 15,000 years ago, during the Ice Age, most of northern North America lay under the grip of colossal ice sheets. The eff ects of the advancing and retreating glaciers can be seen in the headlands of Cape Cod, the Finger Lakes of New York, and the hills o f M ichigan, but nowhere is the g lacier' s mark upon the land more im pressive than in W isconsin. Indeed, the State has lent its name to the most recent series of glacial advances and retreat s--the W iscon sin Glac iation lasting from about 100,000 t o 10,000 years ago. Many times during the past two mill ion years, a time also known as the Pleist ocene Epoch, the climate has fluctuated between warmer and cooler temperatures . During the colder fluctuations, glaciers formed and spread outward from Arctic areas , engulfing most o f northern North America. Each of the major glaciations has been followed by a warmer interglacial period, probably similar to that of today , during which the glac iers melted away. The glacier most recently flowed into Wisconsin about 2 5,000 years ago and reached its greatest extent, covering approx imately twothirds of the State, about 14,000 to 16, 000 years ago before melting back. The retreat of the ice front was interrupted a number of times by readva nces; the last one touched northwestern W isconsin about 10,000 years ago. The extent of this and earlier glaciations in Wisconsin is shown on the maps on this brochure. distances are called errat ics. The material frozen into the base of the flowing ice gouged and scraped th e land, leaving in some areas scratches, called striations , in the bedrock . In other areas stream lined , elonga te hills called drumlins were formed . Wisconsin's stat e capitol sits atop one of these hills. Impressive clusters of them are fou nd in the Campbellsport Drumlins Unit of the Ice Age National Scientific Reserve and in other areas, particularly southeast ern W isconsin The striations and the long axis of the drum lins indicate the direction the ice flowed. W hen the ice melted at the edges of the lobes the sand , silt, cobbles , and boulders frozen in it were released and formed ridges called moraines. Even as the glacier melted back, ice usually contin ued to flow toward its edge, bringing mo re debris w ith it. Occasionally the f low stopped, the ice stagnated , and blocks of ice detached from the glacier were buried in debris. Many of Wisconsin 's lakes lie in the depressions formed by the melting of the buried ice . The mora ines vary greatly across the state. Those in the southwest are usua lly dry, narrow ridges sitting atop the older hills at the edge of the unglaciated Driftless Area. Across the northern counties the moraines form a broad band The advancing ice was channeled into the lowlands now occupied by Lakes Superior and M ichigan, Green Bay, and the Fox River, and it was impeded by the uplands of the Bayfield, Keweenaw, and Door Peninsulas. The ice was thus split into six m3jor lobes as it flowed across the state . The Green Bay Lobe, which had few obstructions in its path, penetrated as far south as present-day Janesville in Rock County. The ice within the lobes was almost always sliding or creeping toward the edges of the glacier, even as it melted. As the ice moved it froze around grains of sand, pebbles, and boulders , picked them up, and carried them along. Boulders that were ca rri ed great of hills and hollows - a poorly drained rocky landscape dotted w ith lakes, marshes , and bogs. The Chippewa Moraine Ice Age Reserve Unit is a particularly picturesque portion of these moraines, containing numerous depressions fi lled w ith lakes, bogs, and marshes . The moraine in Waushara County in the center of the state is similarly pitted with thousands of these depressions, but most of them are dry. Th e rugged, scenic Kettle Moraine in the eastern part of the state is actually a series of moraines formed between the Lake Mic higan and Green Bay Lobes. The Green Bay Lobe also lef t a moraine in Sauk County which bloc ked both ends of a gorge in the Baraboo Hills creati ng Devils Lake. Some mora ines sta nd no more th an 30 feet above the surrounding terrain, but others in t he Kettle Moraine rise to heights of 250 t o 300 feet. of the glacier. Like drumlins, they are usually aligned para llel to the ice fl ow. The flowing meltwater spread fi ne layers of sand in broad pla ins, such as those in Langlade, Rock, and Portage Counties, that today are fertile cash crop farm ing areas .

Ice Age Trail Thousand-Miler Map and Checklist 2021-0330 Using This Map Key to Symbols Connecting Route Ice Age Trail Trade River This map was created by an Ice Age Trail Alliance volunteer based on the Ice Age Trail Atlas and the Ice Age Trail Guidebook (2020 – 2022 Editions) and updates provided by the Ice Age Trail Alliance. If you have questions, corrections, or suggestions, contact IATA volunteer Sue Knopf (graffolio21@gmail.com). Segments or connecting routes where changes have been made since the 2020 – 2022 editions of the IATA publications or are anticipated in the near future are noted on the map and in the list with a star ( ). Because the Ice Age Trail route changes from year to year as volunteers construct new segments and reroute and/or close others, hikers should refer to the IATA website (iceagetrail.org) for the most up-to-date Ice Age Trail information. The e-version of this map is available free from the Hiker Resources page of the IATA website (https://www.iceagetrail.org/hiker-resources/; see More Resources to Explore). It is a PDF file enabled for commenting so that you can write notes or mark segments you’ve hiked using Adobe Reader’s commenting tools. At full size, it is 36 inches by 54 inches. A hard copy version is available from the Ice Age Trail Alliance store (https://www.iceagetrail.org/product /ice-age-trail-thousand-miler-map-checklist/). It is 30 inches by 44 inches. Segment label with segment name, mileage, and map number(s). Mileage noted as “4.3 (0.4) mi” means that the segment length is 4.3 miles including a 0.4-mile connecting route. 4.3 (0.4) mi • 3f Connecting route label with mileage and map number(s) CR 4.5 mi • 33f Means an anticipated or actual Trail or route change since the 2020–2022 editions of the IATA publications. Bifurcation points B A Note about Mileages 65.7 The mileages listed on the map are based primarily on GPS data collected in the field. If you add up mileages and compare the totals to the stated mileages for counties and the entire Trail, you may find small discrepancies (usually not more than 0.1 miles) due to rounding error. Accepting these discrepancies, the Ice Age Trail Alliance recognizes the following total mileages at the time the map was published: • Total Ice Age Trail route, including both branches of the bifurcation: 1224.8 miles. • Total Ice Age Trail route, including the eastern branch of the bifurcation but not the western: 1142.9 miles.* • Total Ice Age Trail route, including the western branch of the bifurcation but not the eastern: 1142.1 miles. 1077.2 Washburn 119.3 (See Barron) Burnett 1023.6 * Because most who apply for “Thousand-Miler” recognition hike the eastern branch of the bifurcation but not the western (both are not required), the distances from the county borders to each terminus are based on this approach.
