Title: Cosmogenic Exposure Ages, Alaska Palaeo-Glacier Atlas
- Point data
- 2011
- Not owned by MIT (Owned by Stanford)
Summary: This line shapefile contains cosmogenic exposure ages from late and early Wisconsinan drift linked to references in the geospatial database. Most 10Be and 26Al ages use the same or very similar production rate. All 36Cl ages use the same production rates. Refer to original reference for all details of age and scaling calculations, in addition to how authors handle erosion rate and snow shielding.This report is an update of the Alaska PalaeoGlacier Atlas. It includes information published since 2002 and is based on a more detailed map scale. In addition to the all-time maximum extent of former glaciers and the late Wisconsinan extent, this update includes the mapped limit for the penultimate glaciation, which generally occurred during the early Wisconsinan. The update also includes a compilation of cosmogenic exposure ages linked to the geospatial database. The Alaska PalaeoGlacier Atlas is a geospatial summary of Pleistocene glaciation across Alaska. Our goal is a comprehensive and consistent overview of former glacier limits across Alaska. Our hope is to facilitate outreach, education, and interdisciplinary research in the fields of geology, geography, biology, and natural history.

Title: Late Wisconsinan Glacier Limits, Alaska Palaeo-Glacier Atlas
- Line data
- 2011
- Not owned by MIT (Owned by Stanford)
Summary: This line shapefile represents the Late Wisconsinan glacier linits (extent). Pleistocene glaciers once covered >1,200,000 km2, from the continental shelf bordering the North Pacific to the northern foothills of the Brooks Range. Late Wisconsin glaciers occupied 727,800 km2 -- nearly ten times the area of modern glaciers, but only 48% of the state. Alaska's glaciers expanded more than 20 times during the last 3 million years in response to cold and snowy conditions. During the late Wisconsin glaciation, when sea level fell approximately 125 m (approx. 400 ft), the Bering Land Bridge was exposed as a broad tundra plain, and much of the state escaped glaciation due to a cold but dry climate. Deposition and erosion by glaciers in the recent geologic past have greatly influenced Alaska's landscapes and ecosystems. This report is an update of the Alaska PalaeoGlacier Atlas. It includes information published since 2002 and is based on a more detailed map scale. In addition to the all-time maximum extent of former glaciers and the late Wisconsinan extent, this update includes the mapped limit for the penultimate glaciation, which generally occurred during the early Wisconsinan.

Title: Late Wisconsin Glaciers, Alaska Palaeo-Glacier Atlas
- Polygon data
- 2011
- Not owned by MIT (Owned by Stanford)
Summary: This line shapefile represents the extent of glaciers during the late Wisconsin glaciation (also known as the Last Glacial Maximum, about 20,000 years ago).

Late Wisconsin glaciers occupied 727,800 km2 -- nearly ten times the area of modern glaciers, but only 48% of the state.

Title: Great Lakes Shoreline (CUSP), Wisconsin 2024
- Line data
- 2024
- Not owned by MIT (Owned by University of Wisconsin-Madison)
Summary: This data represents Great Lakes Shoreline (CUSP) for Wisconsin in 2024. [Shoreline is a dynamic interface between land and water. The cartographic depiction of shoreline is a representation at the time of survey. Continually Updated Shoreline Product (CUSP) provides the most up-to-date shoreline of the United States and its territories. CUSP will identify the most up-to-date surveys for inclusion, employ state-of-the-art technology for cartographic review, attribute shoreline features, and develop a strategy to replace shoreline as it becomes available. CUSP is a separate product from the project-based national shoreline mapped by the National Geodetic Survey (NGS). The national shoreline from the Coastal Mapping Program provides accurate tidal referenced shoreline, aids to navigation, hazards to navigation, and associated cultural and topographic reference data primarily for nautical chart applications. CUSP will only include shoreline and alongshore features that represent shoreline (groin, breakwater, and jetty). CUSP has less stringent data acquisition requirements and quality control measures compared to the Coastal Mapping Program's National Shoreline. Where applicable, CUSP will reference a mean high water shoreline based on vertical (VDatum) modeling or image interpretation using water level stations and/or shoreline indicators. CUSP is built upon contemporary NGS's National Shoreline which comprises approximately one-third of our nation's shoreline and focuses primarily on the most navigational significant areas. CUSP uses and incorporates both NOAA and non-NOAA contemporary sources (Lidar, imagery, and external shoreline vectors) to replace shoreline areas of older vintage. Shoreline continues to be reviewed with contemporary imagery and additional data is being included with the goal of providing a continuous shoreline of our nation and its territories. For additional information, please see the CUSP One Pager.]
