Last Glacial Maximum refugia

Last Glacial Maximum refugia were places in which humans and other species survived during the Last Glacial Period in the Northern Hemisphere, around 25,000 to 20,000 years ago.

European LGM refuges, 20 kya.

  Solutrean and Proto-Solutrean cultures

  Epi-Gravettian culture

Sub-Saharan Africa and Australia were not affected by the glaciation although vast areas of them were too dry for human habitation of any sort, even by the most specialised and well-adapted foragers), and the Americas and New Zealand had no humans at the time. Therefore, the shelters were mainly in Eurasia. Several of them have been studied.
