Title: Cosmogenic Exposure Ages, Alaska Palaeo-Glacier Atlas
Contributors:- Point data
- 2011
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
Contributors:- Line data
- 2011
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

Title: Massachusetts, USA (Zipcodes+4, 2002)
Contributors:- Mixed
- 2002
Summary: TIGER 2002 contains over 27,000,000 ZIP+4 points, each one being linked to a specific street segment. This file has only Massachusetts information but information is available for every state in the GIS Lab, Rotch Library. Call number for this CD is G3701 P8 2004 S7. The files on the ZIP+4 CD are compressed in a .zip format, by state.Each ZIP+4 point was placed on the correct side at the middle of each street segment. In the case of a street segment with multiple vertices, the ZIP+4 point was placed on the appropriate side of the middle segment or middle vertix. Each point has been offset 25 feet, perpendicular to the street segment.
