Lois Parshley’s essay on the last unmapped, mysterious places—Greenlandic fjords, the slums of Haiti, the ocean’s depths, black holes in space—is a long read worth reading. Originally published last month as “Here Be Dragons: Finding the Blank Spaces in a Well-Mapped World” in the Virginia Quarterly Review, it’s been reprinted by the Guardian, in an edited, tighter version, as “Faultlines, Black Holes and Glaciers: Mapping Uncharted Territories.”
