Of course this blog is about creative ways to display data, especially maps, that people can easily digest. It's impossible to figure out exactly what it is we're looking at, even if I did provide a scale bar and north orientation, without key pieces of context.
So what was a basically worthless layer of lines, is now an interesting look at the network of walking trails maintained by the National Park Service. Another key piece of context: It's 60 degrees today. Go out and get some sunshine.
