Making this map was a joy. It is one of a series of nine maps of the same extent, all with different design. I was inspired by Victorian era maps. Some fonts are pretty close to what the U.S.G.S. used on their late 1800s - early 1900s topos. I'm committed to creating one of the fonts that occurs on that period of maps, but of which I had a hard time finding.
Look for that font and a blog post on this map coming this fall, at Petrichor.Studio.
