Great Lakes of the Pleistocene

I've been really busy for the past couple years and haven't really had time to make any maps, which has really sucked. Even my iPad map series came to an end after my iPad decided to commit suicide. I just felt like uploading something.

This is a map I made for a project. I'm currently taking two courses that I decided to combine: Geomorphology and Ice Age Peoples. It shows the distribution of glacial, nonglacial, and pluvial lakes during the Pleistocene (Great Ice Age). It isn't alternate history or anything, but hey, its a map.
