William A. “Bill” Wallace first published The Milepost in 1949 as a 72-page book filled with facts and practical information about traveling the rugged and remote Alaska Highway, the famous road built in 1942 in response to the Japanese occupation of Attu and Kiska islands in Alaska. Wallace named the guidebook after the mileage location posts “that filled such a vital need along the wilderness road.” As Alaska tourism grew, so did The Milepost. In 1962, Wallace sold the book to the owner of the publication that was to become Alaska magazine. By 1975, the burgeoning resource book featured 498 pages.

Morris Media Network bought The Milepost with Alaska Magazine in 1995. It remains the quintessential reference guide for Alaska and northwestern Canada.
