Mapping Sitka is pretty much my identity. I was upset when someone reverted my work because honestly I’ve been working every waking hour for a few months now. It was good though because I needed to step back and not take it too seriously. I’ve had some manic episodes late in life and they unlocked some anger I’m not familiar with. It was actually impressive how mad I got. Anyway, what are these diaries for if not a super personal post? Stay mappy people

The coastline has been my particular interest ever since I started editing the map.
