I had fun exploring historical cartographic styles for the #30daymapchallenge Day 7 theme of 'Vintage". Here is a visualization of elevation and bathymetry in the Salish Sea Bioregion. I used topobathymetric data from the Salish Sea Atlas (arcg.is/0WaK51). I looked at some of my favorite local 18th and 19th century maps for cartographic inspiration and historical toponyms.
