How do you know it was within 600 miles?
Charting the exact location of past tectonic plate movement is inexact science to be sure, as the land itself mutates along the way. The Arctic Ocean is also growing, so it was smaller the further back in time. The 600 mile mark today is close to Ellesmere Island, which is still in ice age, but no longer attached. You need intact land for glaciers to grow. When they go out over water, they break off, which is why ice ages are continent specific. 40-60 million years ago, the top of Northern Canada was where the top of Greenland is today, possibly further north accounting for Arctic Ocean growth.

Link?
Seriously, if you were driving, and the sign said "One Way" you would ask the sign for a link....
What about the glacier over Chicago that melted 20,000 years ago?
Was Chicago, or Canada, within 600 miles of the pole?
If not, how did the glacier survive so far south?
You have a wonderful test case in Greenland, where the ice age originated 600 miles or so from the pole, and pushed ice away from the pole... straight out of the polar circle. Ice on Greenland extends way south of the Arctic Circle, while on Canada you can grow trees hundreds of miles north of the Arctic Circle.
Think about that before asking for another stupid link. The warmers do not like truth. They prefer censorship.
