I recently saw an otherwise normal globe that was probably made in the 60's or 70's. On it I noticed that Greenland had a huge sea in it starting at a fairly narrow inlet somewhere south of Thule and roughly following the shape of the northern half of greenland with only 100-200 mi. of land surrounding. Is this normal for old maps? Due to poor satellite imagery? I should say that the globe focuses on elevation and ocean depth and such which is why I wonder about satellite images. Possibly it's just a poorly printed globe. It's in a building I don't work in much but I should see it next week or so and could maybe find the manufacturer.

I haven't seen that - could you take a photo of that part of the globe? Here is a map I found over the topography of Greenland: http://geology.gsapu....expansion.html

I wonder how much one knew about what it looked like under the ice sheets in the 60-70ies - I don't think it would have based on satellite imagery at that time.

My early-80s globe shows a similar 'sea' much as you describe, labelled as 'Glacial period ice average elevation 2134 metres'. Perhaps the globe-maker had a problem with his colours.
