Question: Maps of Landforms to 100,000 Years Ago?

Dave Van Epps writes, “I am trying to locate maps that together will give me information at approximately 10,000-year intervals, back to 100,000 years ago, of coastlines, glaciers, continents, major rivers and seas.” Presumably he’s looking for the changes wrought by glaciation and ice ages. Is there a resource for Dave out there?
