I started this about a year ago, but after getting through about half of the lakes--after doing everything else you see--I needed a break and set it aside. A few days ago I picked it back up and brought it to here. I spent forever looking for a base map to use for an alternate reality North America map I wanted to do and when I couldn't find what I wanted I grabbed an atlas map and started tracing. The map is much larger than the attached image. But here's where I am so far.
