From a U.S. Geological Survey Announcement:

The U.S. Geological Survey announces it is now possible to see the topography and geography of Alaska in an extensive set of topographic maps dating back to 1899. This recent addition to the Historical Topographic Map Collection provides a comprehensive landscape repository of our northernmost State and shows changes through time, providing essential clues critical in the understanding our Nation’s development.

Approximately 500 maps were published in various portions of Alaska prior to 1950. In preparation for statehood in January, 1959, an intensive mapping program compiled and published more than 7,500 topographic maps. These recent era maps are mostly at 1:63,360 scale (one inch equals a mile) and provide a detailed view of Alaska topography, physiography and culture. The collection of historical topographic maps will provide valuable support to the developing Alaska Mapping Initiative, a multi-agency effort to remap the State of Alaska at 1:25,000 scale.
