Here's one of several maps I made last year tracing the journey of Daniel Greysolon, Sieur du Luth, one of the first white people to visit what's now Minnesota, in 1679-1680. www.stcroix360.com/2024/12/hist... #30DayMapChallenge

I missed a couple days of the #30DayMapChallenge but it was seriously because I was working on a big map project and reading academic articles about deep mapping. Anyway here's one of my favorite places.

Keeping it simple with my second map of #30DayMapChallenge. My favorite linear landscape features: rivers.

Your dad was Jim Mason! Too cool. I have his dissertation, it's amazing. Yeah, often hard to separate the man from the myth around here.
