A recent comment has led me to Bearings: A Geographer's Blog. The blog is "an exploration of our culture, and how humans impact the surrounding environment. This is not an eco-blog, or a policy blog. It simply looks at the landscape around us, interprets its history, and offers commentary on the built environment — in all its beauty and ephemerality."
I can sum it up as what would a blog by J.B. Jackson or Terry Jordan (I mean this as a compliment, to some geographers a comparison to TJ are fighting words) would be like.
The author, Jon, is a fellow National Geographic alum and has written for other publications. Some of his work is available online.
