Welcome to the world of Maphead: Charting the Wide, Weird World of Geography Wonks (Scribner, $25), in which unabashed geography wonk Ken Jennings (yes, that Ken Jennings, the Pacific Northwest native who in 2004 set a record for consecutive Jeopardy! wins that will outlast the pyramids) hosts a lively and entertaining tour of those who share his interestOK, obsession. Combining popular history and memoir in a wry, sort of Sarah Vowell-ish way (only less deadpan and more one-linery, and even funnier), Jennings gives us the stories behind the map-illiteracy crisis (“43% of college freshmen can’t find Canada” and all that media kerfuffle); high-dollar map dealers; the Library of Congress’ Geography and Map Division and its 8,500 cabinets of maps; those who, like 14-year-old Benjamin Salman of Queen Anne, draw maps of self-invented, astonishingly detailed fantasy worlds; various clubs of travel completists whose journeys are checklist-driven (striving to visit, say, the highest points in each of the 50 states); “road geeks” who can tell you everything you’d ever want to know about the U.S. Interstate system; and the Google Earth project and its ultimate goal: visually cataloging the planet’s entire surface on the scale 1 square centimeter = 1 pixel. Jennings explains the phenomenon of geocaching and how Geocaching.com, the global game’s Internet epicenter, is headquartered in Fremont.
