May I immodestly suggest my own Web site? It's an Atlas of the world for
various stages by the LGM, with an accompanying literature review:
http://www.esd.ornl.gov/projects/qen/nerc.html
It's a little out of date (I stopped updating it a few years ago) but not much
has substantially changed in the past several years in terms of our view of
what the late Quaternary looked like.

Hi Clinton,
It might not be exactly what you're looking for, but
I heartily suggest investigating the very well done paleogeographical
materials that Prof. Ron Blakely (Univ. AZ) has put together; which includes
plug-ins for NASA World Wind

"The globes presented in this series show how Earth may have appeared
over the last 600 million years (Ma). The global views were prepared
from rectangular projections drawn at a resolution of 3000x1500 pixels
for each of the 26 time slices (small files of the rectangular maps are
also included). Topography was "cloned" from digital elevation maps
of
modern Earth from the USGS. Colors were adjusted to portray climate and
vegetation for the given time and location. The modern Earth was also
drawn in this manner using a color pallet derived from satellite images
created by ARC Science of Loveland, Colorado."
Includes Precambrian to the present

visually stunning and very informative.

Does anyone know where I might find a global map, preferably in GIS format,
showing the length of time since last glaciation? Ideally this would be a
continuous measure of time, illustrating the retreat of the last glaciation,
but a coarsely categorized map would be useful also. Thanks.
Clinton
