Hal Linder '58 paid $4,000 for his bachelor's degree in geology at MIT. In six decades following graduation, Linder got his money's worth, surveying and prospecting on all seven continents, eventually uncovering a gold mine in Nevada containing over 1.2 million ounces. Linder chronicles his adventures above and below the earth's crust in a new book, Wild Places: The Adventures of an Exploration Geologist.
