The Milepost is an extensive guide book covering Alaska, the Yukon, the Northwest Territories, and British Columbia.
It was first published in 1949 as a guide about traveling along the Alaska Highway, often locally referred to as "The ALCAN".
The Milepost is packaged and distributed like a book (2008 edition: ISBN 978-189215431-6), but like the Yellow Pages it includes paid advertising.
Newer additions include special sections on selected areas popular with tourists, such as the Kenai Peninsula.
It is also exhaustively cross-indexed and maps and charts are provided so that travelers can determine the total driving distance between any two points covered by the guide.
